Supervisor: dr hab. Katarzyna Szarłowicz
Faculty of Energy and Fuels

Abstract:  Sediments are an integral part of the water ecosystems. Thanks to their very good sorption properties, they accumulate toxins including radionuclides that are found

in the immediate vicinity of the water reservoir as well as those resulting from the so-called long-range impacts. Therefore, they constitute both a “toxin storehouse” and an archive of the past. The main aim of the doctoral thesis will be to assess the accumulation and contamination of radionuclides in sediments taken from mountain lakes and their use to interpret environmental changes in water ecosystems. The individual research stages will include: the sampling of the sediments’ core, preparing them for alpha and gamma measurements, radiochemical analysis for alpha radionuclides, radiometric measurements, results preparation using statistical methods and their interpretation in the aspect of environmental changes that took place over 200 years. An important element of the research will be the optimization the method for plutonium determination in sediments’ samples. The tests will be carried out based on alpha and gamma spectrometry. It is planned to take measurements of radionuclides from radioactive series and the anthropogenic, such as 238Pu, 239 +240Pu, 137Cs and 241Am.

Research facilities: Research in the doctoral thesis will be carried out using high-class radiometric equipment as well as basic laboratory equipment. The experiments will be carried out at the Laboratory of Chemical Analyzes and Radioactivity in the Environment at the Faculty of Energy and Fuels and the Radiochemistry Laboratory located at the Energy Center, AGH. The most important laboratory equipment includes: two HPGe gamma spectrometers Broad Energy type (energy range from 5 to 3000 keV, germanium crystal with an area of ​​3800 mm2, with a window made of carbon composite, gamma spectrometer with coaxial detector (HPGe), detector efficiency of 20% (1.33MeV), two alpha spectrometers, model 7401 with PIPS detector 450 mm2 and FWHM <18 keV (5.4 MeV), a set with a Geiger-Muller detector model Inter GP35, radiometer of radioactive contamination; scintillation spectrometer with NaI detector, two-station set for deposition, electrodeposition and coprecipitation of alpha radioisotopes, 8-position microwave digestion system Multiwave Pro Anton Paar.

4. Comparative research of water electrolysis and hydrogen methanation in relation to the requirements of the energy storage process (Power to Gas)

Supervisor: dr hab inż. Mariusz Łaciak, prof. AGH.

Faculty of Drilling, Oil and Gas

Abstract: Power to Gas (PtG, P2G) is a technology that converts electricity into other forms of energy for long-term storage. The conversion of electric energy into chemical energy used in PtG technology takes place in the process of electrolysis of water, whereas the production of methane takes place in the methanation process. The proposed research issue will concern the comparison of individual types of solutions for electrolysis and hydrogen methanation in the aspect of energy storage capacity. The processes that will be analyzed are process of alkaline electrolysis (AEL), membrane electrolysis (PEM) and solid oxide electrolysis (SOEC), as well as catalytic and biological methanation processes. The purpose of these analyzes will be to examine the possibilities of improving the efficiency of electrolysis and methanation processes. This will optimize the energy storage process by exploring the technological possibilities of increasing the amount of methane obtained and increasing the permissible hydrogen content in individual elements of the gas system.

Research facilities: The Department of Gas Engineering has a wide laboratory base and experience in conducting research in the field of gas technologies. The experience gained comes from the implementation of research grants and work carried out on behalf of the gas sector companies.

5. The impact of lithology and the mechanism of rock damaging on the morphology of the separating and post-failure fractures

Supervisor: dr hab. Marek Rembiś

Faculty of Geology, Geophysics and Environmental Protection

Abstract: Morphology of the surfaces of separating fractures, in the geotechnics terminology called roughness, is one of significant factors in the classification of rock massifs. Its role within the rockmass have a considerable impact on rock displacements transversal to the shearing direction, and also on the rock resistance to sliding along discontinuity surfaces, and in many types of rocks on preserving the rock post-failure residual strength. A substantial growth of scientific interest, arising from introducing new measuring techniques, has in last years been focused on the determination of characteristic parameters of the fracture surface morphology and on their relation to rock properties. The goal of the research includes the identification of the relation between the morphology of the separating surfaces and the form of the post-failure fractures on one hand and, on the other hand, between a type of the damaging mechanism of their formation and such petrographical features of the rock damaged as its structure, texture, mineral composition and the degree of alteration of its mineral components. The experiments of the Ph.D. student will include generating 3D-oriented surfaces of the induced failure in rocks with diversified lithologies subject to the tensional, compressive and shearing stress tested on large-format rock samples with a stiff testing machine. The determinations of strength parameters will be followed by petrographic observations and microhardness measurements, then by analyses of morphology (roughness) of both the separating and the post-failure surfaces using a laser profilometer. The petrographic rock features will be statistically related to the geometrical parameters of the separating surfaces. Considering a substantial complexity of the morphology of the separating surfaces, the roughness will also be characterized applying the fractal analysis with determining the fractal dimension as the index of isotropy of a fracture surface.

Research facilities: The material for the investigations will be obtained by the Ph.D student in outcrops and opencast mines in the course of research being carried out at the Department of Hydrogeology and Engineering Geology. The equipment required, among others a rock strength testing machine with a feedback control system, a microhardness tester with Knoop and Vickers indenters, a petrographic microscope with an on-line image analysis system, are available in-house, while a laser profilometer is on the purchase list for 2019. If a need arises, additional investigations can be conducted using the equipment, for instance a scanning microscope, of the Faculty Laboratory.

6. Modeling prospects of energy transition in Poland

Supervisor: prof. dr hab. inż. Wojciech Suwała

Auxiliary supervisor: dr inż. Artur Wyrwa

Faculty of Energy and Fuels

Abstract: The subject of the research is the development of a fuels and energy system model covering the whole economy of the country, broken down by sectors, which will result in a complete energy balance. Changes in the fuels and energy markets are related to the implementation of environmental/ climate/energy efficiency policies and apply to the whole economy. This raises the necessity of development of the model covering all sectors of the economy taking into account the relationship between them, and theparticular technical and economic characteristics of individual sectors. The model has to enable analysis of the impact of certain policies, such as: a) increase of the share of renewable energy sources in power generation structure; b) reduction of CO2 emissions from the economy; c) increasing energy efficiency; d) increasing the flexibility of the production and transmission of energy (electricity and heat), following the energy transition of the country.

Research facilities: The Faculty has both software and hardware required for modelling fuels and energy systems. Submissions of proposals for specific projects and grants is expected.

7. Revitalization of degraded areas - environmental, spatial, technical, legal, social and financial aspects.

Supervisor: dr hab. inż. Anna Ostręga, prof. AGH

Faculty of Mining and Geoengineering

Abstract: Degraded areas can be a threat and an opportunity. Revitalization is a process aimed at reducing threats and using the potential for socio-economic development. Methods to reduce soil, earth, water and air pollution require continuous improvement, which aims to increase efficiency, environmental friendliness and cost reducing. Post-industrial areas, including post-mining, also have potential in the form of, for example, historical infrastructure, post-mining reservoirs, overburden dumps or waste heaps. Their use for socio-economic development is a multi-aspects process (spatial, technical, legal, social and financial) therefore it requires the involvement of many stakeholders. It requires also developing optimal scenarios, not only for revitalization, but also for maintaining the products of this process.

Research facilities: The Faculty of Mining and Geoengineering has the following facilities:

  • Laboratories enabling research on various aspects of revitalisation of degraded land, e.g. Laboratory of Soil and Rocks Research, Laboratory of Hydrology and Geoigineering Hydraulics, Geotechnical Research Laboratory, Laboratory of Blasting Works and Environmental Protection.

  • Research projects for the socio-economic environment in progress, for example, the "Tarnowskie Lakeland" – an innovative project of coherent revitalization of the sand and gravel open pit complex for recreational, tourist and nature functions (from 2013 until now).

  • International research projects in progress: MIREU – Mining and Metallurgical Regions of the European Union (2017–2020, Horizon 2020); ReviRis – Revitalising Post-Mining Regions: Problems and Potential in RIS Europe (2020–2021, EIT KIC).

8. Influence of indoor swimming pool occupancy on water evaporation from pool surface based on experimental investigations

Supervisor: dr hab. inż. Dariusz Obracaj

Faculty of Mining and Geoengineering

Abstract: Previous methods for predicting water evaporation rate in indoor swimming pools use the results of qualitative and quantitative research based on models or real objects. Besides external sources of heat and mass, water evaporation phenomenon depends not only on physical parameters of water and air but also on the degree of disturbance of water surface associated with a number of people and their activity as well as other moisture sources beyond the water pool. For engineering applications, the prediction of water evaporation rate is essential to the design of low-energy air-conditioning systems for such buildings. Experimental and model studies will focus on specifying particular factors affecting the exchange of mass and heat at the air-water interface for real conditions of the objects. The results obtained will allow for the verification of both the existing evaporation models and the determination of the ability to offset latent heat gain by ventilation air of an indoor swimming pool.

Research facilities: Experimental investigations will be carried out at the experimental setup located at the WGiG. The experimental setup enables testing mass and energy exchange at the air-water interface in an adiabatic enclosure, taking into account both internal and external heat sources. The results of the experimental tests will be used to verify model research.

9. Use of computational fluid mechanics methods in optimising the cooperation of spraying systems with ventilation systems

Supervisor: dr hab. inż. Dariusz Obracaj

Faculty of Mining and Geoengineering

Abstract: Spraying systems often work with ventilation systems. Sprinkling as a method to reduce dust concentrations around emission sources is used in extracting, processing or using raw materials in technological processes. Ventilation and dust removal techniques are used simultaneously with sprinkler systems. The issues of velocity fields forming near sprinkler systems are not sufficiently recognised so far. These installations are designed separately and do not include mutual interaction in practice. The research will focus on the use of computational fluid mechanics to calculate the impact of spraying system parameters on the movement of solid particles, droplets and gas in ventilated spaces. Obtained results will allow the development of principles for the selection of individual components of the analysed installations as well as increasing the efficiency of their operation while reducing energy consumption.

Research facilities: Research will be carried out using the ACK CYFRONET AGH computing resources. The grant has been launched as part of the PLGrid infrastructure (The Polish Grid Infrastructure) for this purpose. Validation of numerical models will be carried out based on the results of experimental investigations thanks to cooperation between WGiG and industrial enterprises.

10. Analysis of air flow in the tunnel using simulation and experimental study

Supervisor: dr hab. inż. Marek Borowski

Auxiliary supervisor: dr inż. Piotr Życzkowski

Faculty of Mining and Geoengineering

Abstract: CFD (Computational Fluid Dynamics) computational fluid calculation methods are used in many fields of technology. The advantage of CFD methods is the ability to analyze two- and three-dimensional flows, for which there are no analytical solutions. The basic limitation of computer modeling is the necessity to validate the turbulence models used, usually experimentally. This is due to the fact that none of the turbulence models developed is universal, contains a number of simplifying assumptions and should be verified experimentally for a specific issue.

As part of the research, experimental measurements and numerical analyzes of air flow in real conditions and laboratory models in a tunnel or underground garage will be conducted, which are ventilated with a dedicated ventilation system.

In real conditions, the flow in these objects is three-dimensional and turbulent. When considering turbulent flow, the mathematical model describing fluid motion usually consists of equations resulting from the principle of conservation of momentum and mass (Navier-Stokes equations and continuity) and additional equations constituting turbulence models. It is a valid and up-to-date task to verify existing turbulence models for specific applications. Verification of the results of numerical simulations in tunnel or underground garage conditions is very difficult and usually only possible for global parameters. Therefore, an alternative is experimental measurements performed on laboratory models using the 3D velocity field measurement tool, which is the PIV digital image anemometry (Particle Image Velocimetry).

Abstract: Life cycle assessment LCA is an environmental management tool that enables comprehensive and holistic identification and evaluation of potential environmental aspects and impacts throughout the entire product life cycle, i.e. from extraction of natural resources, their processing, manufacturing of a product, distribution, use, until end-of-life phase i.e. waste treatment. In other words, this methodology identifies and quantifies the environmental impacts of the product "from cradle to grave”, or “from cradle to cradle" if waste is recovered. The LCA methodology is also used to assess environmental aspects of technological processes as well as waste management systems. The aim of the proposed research will be to thoroughly track the entire municipal waste chain, starting with collection, processing with the production of alternative fuel, distribution of refuse delivered fuel (RDF) and its use in the technological process of clinker production in cement plants. There are few LCA studies on the production of alternative fuels and LCA studies of clinker production, while the novelty of this research will be to comprehensively cover and follow the whole value chain of waste from its collection to the incorporation of substances from waste into clinker, emissions to the air and to final waste. In addition, there are no LCA studies for the clinker production process, in which up to 90% of the fuel comes from waste.

17. Large-scale waste fires and their impact on the environment

Supervisor: dr hab. inż. Katarzyna Grzesik

Auxiliary supervisor: dr inż. Mateusz Reszutek

Faculty of Mining Surveying and Environmental Engineering

Abstract: In Poland, in recent years, there have been large-scale fires of waste at landfills, storage places and waste treatment installations, as well as in facilities with unregulated status. The Central Statistical Office reports that 126 fires occurred in 2015, in 2016 - 117, and in 2017 - 132 fires. Data for 2018 are not yet available, it is estimated that in the first half of 2018 about 120 waste fires occurred. In 2019, despite significant changes to the legal provisions in the field of fire protection, there are still fires in waste installations. Such numerous and large fires of landfills and other waste management facilities are unprecedented on a global scale and so far no research has been conducted into the impact of such events on the environment. The burning of large amounts of waste in uncontrolled conditions causes the release of substances into the air, soils and waters. The extent of environmental pollution and the deterioration of the environment quality due to fires is unknown, as no comprehensive research on the impact of landfill fires on the environment has been conducted so far. The aim of the project is to: make a detailed inventory of the waste fires together with type and amounts of combusted waste, elaboration of the selection methodology and selection of several representative burnt sites for detailed research and analyses, development of environmental impact indicators for waste fires and methodology for estimation of the impact of large-scale fires on environmental quality, as well as estimation of the environmental impact of waste fires on a regional and cross-border scale.

Supervisor: dr hab. inż. Tomasz Bergier

Faculty of Mining Surveying and Environmental Engineering

Abstract: The Blue-Green Network (BNG) is an integrated and interdisciplinary concept for the development of urban space. Its purpose is to maintain the continuity of ecological and hydrological processes taking place in the designated area, thus influencing the wide use of ecosystem services. The first stage of the work will be identification of the blue-green network (BGN) in the Municipality of Krakow along with its components, in particular the system of rivers (present and historical) and their valleys, water bodies and ponds, as well as the associated green areas. On the basis of field studies and existing planning documents, the Krakow BGN will be defined: its current and target range –crucial for the effective provision of ecosystem services in the entire city space. The main scientific objective will be to create a model of engineering solutions (especially green infrastructure), which will enable closing the discontinuity in the existing BGN in the city of Krakow, and increasing the effectiveness of its provision of ecosystem services (first of all rainwater retention, but also improvement of microclimate, reduction of the heat island effect, etc.). Several locations will be selected, characteristic for the Krakow BGN, where designs of prototype “blue and green” solutions will be created. Another research objective will be to identify and describe benefits provided by these prototype systems and to cover the entire area of BZS and the city. The implementation of the research tasks described above will allow to verify the scientific thesis: the green infrastructure solutions are an important and effective tool of the urban rainwater management. The implementation of the above mentioned concept by the Board of Municipal Greenery in Krakow (ZZM) will provide the basis for a new organization of urban space taking into account sustainable water management and other challenges of modern municipal management.

It may soon turn out that traditional technologies and current technical solutions will be insufficient to operate in safe conditions. The reason for this state is the prediction of a significant increase in climatic and gas and geodynamic hazards. Multi-level (Two-level) structure of mine ventilation network might become the solution for improving work safety. However, it requires carrying out an in-depth analysis and formulating the principles of transforming a single-level vent network into a two-level one. Applying multi-level network and vertical ventilation connections within mining divisions may turn out to be a means of minimising the adverse influence of aerological threats and offer a chance to continue exploitation if other technical and technological solutions fail. Therefore, there ought to be developed ventilation solutions that take into account location, structural and organisational model as well as the technical infrastructure of the mine in respect to the mitigation of aerological threats. The assumed result of the thesis (the aim) is putting forward such recommendations of specific solutions that can be implemented not only in one mine but also on a global scale.

Research facilities: The research issue (together with the preliminary definition of the topic) has received a positive recommendation of the Steering Committee and has been qualified for the next stage of recruitment for the Interdisciplinary Draft of Implementation Doctorates (PhD) for the employees of KGHM Polska Miedz S.A.. Thus it has been ensured that this research can be carried out at the divisions of KGHM Polska Miedz S.A.

21. Studies of air distribution in rooms with the use of an experiment and simulation.

Supervisor: dr hab. inż. Marek Borowski

Auxiliary supervisor: dr inż. Michał Karch

Faculty of Mining and Geoengineering

Abstract: One of the most important tasks of ventilation systems is the distribution of air in the room and the fight against harmful emissions. Separation of air in rooms depends on two factors to which the conditions of the kinetic impact of air streams in the room can be considered, including supply air flows and disturbances (eg convection streams), and geometric conditions, i.e. the size and shape of the room, the location of supply and exhaust openings and the distribution of sources interference. Therefore, in ventilation of rooms, the issues related to the distribution of air in the room are of particular interest. The diffusers and the supply air jet can be characterized by a series of parameters that in the proposed issue will be subjected to simulation and experimental tests. In this type of tests, the range of the supply stream L is defined as the distance from the place of air outlet from the diffuser to the place where the air velocity in the axis of the stream reaches the value equal to the so-called. VL death rates. For a given diffuser, the so-called limit distance L 0.2.

22. Develop a method of supporting decision-making processes in the design of copper bed exploitation in KGHM P.M. S.A., by simulating the behavior of the rock mass on the base of the numerical modeling, in the aspect of geomechanical hazards.

Supervisor: dr hab. inż. Zbigniew Niedbalski, prof. AGH

Auxiliary supervisor: dr inż. Ewa Warchala

Faculty of Mining and Geoengineering

Abstract: When designing the exploitation of copper ore deposits on the Przedsudecka monocline, in the geomechanical hazards conditions including the rockburst, all decisions are made by specialized teams of experts in the field of mining. This applies to "Complex Operational Projects" as well as "Detailed Operational Projects". Such procedures result from the lack of unambiguous parameters allowing to describe the behavior of the rock mass during the operation. So far, methods have not been developed to assess the level of seismic hazard in prognostic terms in terms of determining the time, place and energy of a given shock - similarly to the rest as in the case of seismology for earthquakes. Currently, as a result of many years of experience with certain probability, it is determined in the forecasts of the region of increased seismic activity and its energy level. The use of advanced computational techniques in connection with the use of a properly constructed rock mass model describing real geological and mining situations may affect a more complete determination of deformation and stress characteristics of the rock mass and thus improve the accuracy of seismic predictions. As a result of two years of work was created a three-dimensional model of the deposit fragment (RU-XIX/1 field), close enough to the real one that after loading it, performing the calculations, the obtained three-dimensional results proved to be be very close to flat results presented in analytical methode in the theory of "Pressure waves". It allows, by means of further research, to show whether such an approach to the method of reservoir modeling, with the support of numerical methods and scientific authorities in the field of mechanics (numerical modeling) and mining, create a tool by which it will be possible to simulate the effects of exploitation in the form of stress distribution of roof layers basic, already at the design stage.

Research facilities: KGHM Polska Miedź S.A. Rudna Branch (implementing the results of work) will make available the data in the form of digital maps of the deposit and other materials for conducting research. It will be possible to carry out research based on newly designed operating fields, but also it will be possible to calibrate the model based on the currently completed and currently conducted in the plant the selection works. Faculty of Mining and Geoengineering has laboratory facilities in the field of mechanical testing of rock properties and in the field of advanced numerical calculations of rock mass behavior in various geological and mining conditions.

23. Analysis of the impact of the speed of progress of the mining front on the possibility of limiting the reconstruction of mining excavations in the conditions of occurrence of rocks with lowered geomechanical properties. Optimization of the technology of drilling and securing of excavations in conditions of weak roof rocks.

Supervisor: prof. dr hab. inż. Marek Cała

Auxiliary supervisor: dr inż. Agnieszka Stopkowicz

Faculty of Mining and Geoengineering

Abstract: The analysis of the experience gained during the observation of technological processes when starting the mining on a new field at a depth below 1200 m b.g.l., in particular problems with the maintenance of gallery excavations adjacent to the field, as well as mining excavations allowed to formulate the following thesis:

1. Problems with maintaining the floor slab are related to the presence in the roof of rocks with increased porosity, fissuring and reduced strength parameters and insufficient securing of the roof through the anchor housing.

2. The speed of progress of the mining front has a significant impact on the maintenance of excavations in conditions of weak roof rocks

3. Optimization of the speed of the front and housing progress will significantly improve the stability of the roof in conditions of weak rock mass

The aim of the study is the definition of the relationship between the speed of progress of the mining front in the areas of unfavourable mining and geological conditions, and sometimes the maintenance of mining excavations without the need to carry out reconstruction and determining the minimum speeds of the mining front. On the basis of the analysis of geomechanical properties of rocks, the assessment of the impact of the time of maintenance of excavations on the properties of the rock massif, an alternative method of building these excavations will be proposed.

Research facilities: KGHM Polska Miedź S.A. Polkowice-Sieroszowice Branch (implementing the results of the study) will provide data and materials for conducting research, it will be possible to carry out research on selected research plots. WGiG has laboratory facilities for testing the properties of strength and deformation rocks, load tests of anchors, and conducting modern simulation tests (2D and 3D numerical tools) that represent the behavior of the rock mass in the conditions of the progressing mining front.

24. Protection of industrial heritage in the process of revitalization of mining and metallurgy regions.

Supervisor: dr hab. inż. Anna Ostręga, prof. AGH

Faculty of Mining and Geoengineering

Abstract: Industrial heritage is a non-renewable resource. The landscape of mining and manufacturing regions is rich in various objects created for the industrial activities: mining plants with shaft towers, metallurgical plants, waste facilities and open pits. The subject of the doctoral dissertation will be the “Old” and “New” Copper Basin. The current method of protecting and exposing industrial heritage is not satisfactory, especially with regard to the mining and metallurgical industry, not only on the scale of the region or the country, but also the world. Solutions related to inventory of industrial facilities and their valorization, determination of criteria for selecting objects worth preserving, determination of new functions for them, elaboration of economic and financial analyzes for the adaptation of selected objects require solutions. The results of the doctoral dissertation will be used in KGHM Polska Miedź SA, which will successively close down individual branches of copper mines and backfill mines from the traffic, as well as in the municipalities of the so-called Legnicko-Głogowski Copper District.

Research facilities: The Faculty of Mining and Geoengineering has the following facilities:

Research projects for the socio-economic environment in progress, for example, the "Tarnowskie Lakeland" – an innovative project of coherent revitalization of the sand and gravel open pit complex for recreational, tourist and nature functions (from 2013 until now).

26. Asset optimization modeling of multi-horizontal natural gas reservoir.

Supervisor: prof. dr hab. inż. Stanisław Nagy

Faculty of Drilling, Oil and Gas

Abstract: The subject of the PHD thesis will be asset optimization modeling of multi-horizontal natural gas reservoir. The essence of the research issue will be the development of an integrated optimization system that includes such elements as:

- providing information about reserves and generating production forecasts;

- development of a two-phase flow model in wells with a completion module to optimize production of water,

- modeling of gas treatment processes on the surface,

- process optimization, exploitation with the development plan of a rational production and reservoir management system.

The main issue of the proposed problem of the PHD thesis will the development of an optimization module for surface processes along with a flow optimization system. As part of the PHD thesis, it is planned to build a dynamic simulation model of the gas reservoir. The dynamic simulation model should include the BTEM component - Bioreaction Transport Engineering Model. Based on the dynamic simulation model, there will be prepared scenarios assuming different variants of gas production. In addition, the process of preparing a dynamic reservoir model is planned to identify natural fractures and model them using special numerical modules. As part of the PHD thesis, an uncertainty analysis will be carried out, using, among others, differentiated distributions of petrophysical parameters, saturation of the reservoir medium and PVT data. Assumptions of the developed production system be verified in the process numerical simulator. This should enable determination of parameters to optimize the process. This will also be used to optimize the entire reservoir operation process. An innovative element of the work will be an optimization system combining reservoir optimization layers, wells and surface installations combined with the gas collection and transport system. Currently, the combination of reservoir optimization and optimization of the two-phase flow process seems to be a reasonable method of using the reservoir energy. The result of the works is the optimization of the entire system in the aspect of minimizing costs and maximizing from exploitation and development of the gas field.

28. “U shape” wells systems supported with multistage zipper fracturing treatment used to make CMB multi horizon available for extraction.

Supervisor: prof. dr hab. inż. Stanisław Nagy

Auxiliary supervisor: dr inż. Rafał Smulski

Faculty of Drilling, Oil and Gas

Abstract: The doctorate thesis will include, in particular, the design of an innovative "U-shape" system of wells, a system of two horizontal wells and one vertical well for the simulation of "zipper frac" hydraulic fracturing. The design of wells construction (eg length of the horizontal section) will be appropriately modeled along with the selection of casings, including drilling technology. The next stage will be modeling the hydraulic fracturing treatment in the "zipper frac" technology. The innovation of the frac treatments consists in the alternate use of fluids and backfill. It should be noted that this type of fracturing has not yet been carried out in Europe, nor has such a treatment been considered on such a scale in such wells system. An optimization model will be built for the process as a function of the objective of maximizing the extraction of methane from coal seams. A new pumping system will be proposed, adapted to the new constructions of wells and diameters of the last columns of casing pipes. Estimated production profile will be determined by the innovative "zipperfrac" technology in the construction of U-Shape wells. The result of the work will also be an optimization model of zipper frac technology for the CBM system in the Gilowice area. It is also planned to take into account economic factors in the project and to compare possible outlays to carry out the drilling task of the U-Shape well system together with costs to carry out the "zipperfrac" fracturing phase, the testing stage and cash return possibilities through methane production. This PhD thesis will allow for an innovative technological solution that will allow the optimization of well construction, an innovative approach to the zipperfrac fracturing process, as well as the possibility of an innovative approach to pumping / exploitation of reservoir water and consideration of the most optimal pumping system. It is planned that the results of the PhD thesis will be able to be implemented as part of the exploration and exploitation activities of PGNiG SA.

29. Present rock mass stress state in the Międzyrzecze reservoir concession in view of well data.

Supervisor: dr hab. inż. Dariusz Knez

Faculty of Drilling, Oil and Gas

Abstract: CBM exploration and appraisal under the Międzyrzecze concession granted lately to the Polish Oil and Gas Company have provided a better understanding of the geology of the region. Nevertheless, further investigation of the related geomechanical issues is much needed. Although the normal and strike-slip regimes appear to predominate throughout most of Poland, the hydraulic fracturing treatment carried out in the Gilowice wells under the Międzyrzecze concession has demonstrated the presence of a strike-slip/reverse faulting regime there. The area of study is important from a present-day geodynamics perspective in view of the long-lasting coal mining activities carried out in the region which obviously must have disturbed the in situ stress field. An analysis of the stress directions and magnitudes within the study area with the use of MEM developed for all available wells should reveal the present stress regime. Moreover, it is an important aim of this study from a future GZW well design and optimization perspective to define empirical relationships in connection with unconfined compressive stress (UCS) and the static corrections for elastic properties, and also to answer the following question: which model best explains the failures observed in the wells during drilling? The pure elastic model which does not take into account the interaction between pore pressure and stress during drilling or the poroelastic model which does?

30. Assessment of the possibility of application Coriolis mass flow meters for custody transfer of LNG in Small Scale by dynamic methods.

Supervisor: dr hab. inż. Mariusz Łaciak, prof. AGH

Auxiliary supervisor: dr inż. Krzysztof Łodziński

Faculty of Drilling, Oil and Gas

Abstract: The LNG market of a Small Scale is currently estimated at about 70 000 tons of LNG per year in Poland. Over the next decade, it is estimated that it may even rise to 300 000 tons of LNG per year. At present in Poland and in the world this market is limited to buyers who are interested in buying at least one tanker to regasification plant, while the market potential concerns such a future customers who would be interested in receiving smaller amount of LNG sales in the future through scale effect and it could increase significantly. For this purpose accurate custody transfers are needed that would reliably enable the measurement and custody transfer in the supplier-carrier-recipient chain and at the same time would be deprived of the effect of “aging” of LNG or the dangers of the two-phase flows results. As on a linear gas measuring infrastructure the idea of using mass flow meters adapted to cryogenic liquids seems to be natural example. Such capabilities in the last decade can give Coriolis flow meters that use the Coriolis force phenomenon to measure mass flow rates. In this case, it is necessary to carefully examine and develop: 1) Metrological characteristics of modern Coriolis mass flow meters, 2) Development of measurement procedures for cryogenic liquids including LNG, 3) Determining the principles of measurement consistency for cryogenic liquids including LNG, 4) Establishment of numerical criteria for the accuracy and measurement stability of Coriolis flow meters.

31. Investigation of reservoir fluid density during oil and reservoir water flow in production tubings.

Supervisor: dr hab. inż. Paweł Wojnarowski

Faculty of Drilling, Oil and Gas

Abstract: The aim of the study is to investigate the influence of the presence of reservoir water in production tubings on the density of reservoir fluid in oil wells. At a given flow rate, a certain amount of water is taken out with the oil, and the remaining water can be deposited in the well, affecting the operating conditions and properties of the transported fluids. The research results will allow forecasting how the density of the reservoir fluid changes at a given fraction of reservoir water and at a given flow velocity through the production tubings. This will allow future design of operating conditions in an even more effective manner, which will results increase in the recovery factor of oil field. The algorithms developed during the doctoral thesis will allow in the future optimization of the process of exploitation of oil wells, when reservoir water will start flowing into them. Problems with the transport of reservoir water in the crude oil stream are increasingly observed in wells in the BMB field.

32. The concept and design of a modular natural gas mine - installation of surface gas preparation for transport.

Supervisor: dr hab. inż. Czesław Rybicki, prof. AGH

Auxiliary supervisor: dr Andrzej Janocha

Faculty of Drilling, Oil and Gas

Abstract: The aim of the work is to analyze issues related to the reduction of unnecessary devices (optimization of the selection of necessary devices) and to design individual parts (modules, skids) so that they can be easily combined and selected in terms of work parameters. An important feature of this solution is the ease of changing the scope of operation of the installation related to the fact that during the operation of the reservoir parameters, gas and water expenses change over time, as well as pressure and temperature drops, which in the future entails an investment related to the modernization of the installation maintain the appropriate quality of gas entering the Transmission System or final recipient according to the relevant Standard. The algorithms developed during the PhD course will allow for the creation of several variants of "modules" depending on the scope of work parameters, supported by process calculations and the entire economic analysis. The construction of a standard Natural Gas Mine is a huge undertaking. Many investments are carried out in forest areas or inhabited by people, therefore each investment is also examined in terms of its impact on the environment. In connection with the above, one should look for new design and technological solutions to enable the development of deposits in hard-to-reach places as well as those where low drilling costs occur. Very large reservoirs of 50-100 m3/min from the well are a rarity today and for production from small deposits of 5-20 m3/min from the well it is necessary to optimize the process of managing and maintaining gas facilities.

Research facilities: In the implementation of the research problem, good computer facilities will be needed as part of the doctoral thesis. The Faculty of Drilling, Oil and Gas AGH in Krakow is in possession of a number of computer programs for performing calculations related to the process of gas preparation and optimization of these processes in terms of the design of a modular surface installation. From information obtained from PBG Oil and Gas Sp. z o.o. the company has professional versions of ChemCad and Hysys. programs, which can be successfully used in the implementation of the topic. Hysys programs from Aspen Tech or ChemCad are simulators of chemical processes used for mathematical modeling of chemical processes for unit operations (modules) to full chemical plants and refineries. The programs allow to perform many basic calculations of chemical engineering, including mass balance, energy balance, steam and liquid balance, heat exchange, mass transfer, chemical kinetics, fractionation and pressure drop. It can therefore be concluded that there should be no problem with access to professional computer programs.

Abstract: The modern approach to project management in the oil and gas industry assumes utilization of history-matched dynamic models of fields. Given models allow for production forecasting and optimization. Nowadays this solutions is considered as industry standard on the Norwegian Continental Shelf but a problem about uncertainties related to models is still valid. Mentioned models are created based on input parameters and each of them has its own uncertainty. This situation causes that a final result of reservoir simulation is also uncertain. From a practical standpoint uncertainty analysis around input parameters and final results is very important for investment decisions. In the oil and gas industry each investment decision triggers big financial consequences counted in millions of dollars.

Faculty of Drilling, Oil and Gas

Abstract: The aim of the study will be to examine selected plastics in the following areas in particular composite materials (RTP, GRP) with respect to their possibility of being used as a material for the construction of gas pipelines. The research scope of the doctoral dissertation will focus in particular on analysis of the problem of permeability through walls of gas pipelines built of those materials, both natural gas and mixtures of natural gas with hydrogen. This is a major problem that requires to carry out a series of studies and experiments. Further dynamic development „Renewable Energy Sources” (RES) will force the solution of the important problem of energy storage. It seems that „Power to Gas” development technologies in Poland are necessary to increase the use of RES. Taking into account the specific properties of hydrogen, before it is directed to the gas networks, it is necessary to conduct many tests including those concerning penetrability through walls of the gas pipeline. The scope of work will include, among others, carrying out a series of theoretical calculations for the determination of the permeability values of natural gas and other gaseous fuels through the walls of the pipeline (depending on the material gas pipeline is made of and pressure range) and confront these results with laboratory and 'field' results, where, under field conditions on the selected technological objects of the Polska Spółka Gazownictwa (PSG), it is planned to carry out appropriate permeability tests.

38. Analysis of factors and mechanisms affecting abnormal wear of drill stem components.

Supervisor: dr hab. inż. Jan Ziaja, prof. AGH

Abstract: The main research goal will be to analyze the leading causes of excessive wear of corrosion-related drill stem components. Detection of vision and corrosive factors in the borehole and development of precise methods for measuring the speed of corrosion and the possibility of their performance directly in the borehole, i.e. in real time.

39. Development of a methodology for numerical simulations verification for selected thermal and fluid flow problems.

Supervisor: dr hab. inż. Marek Jaszczur

Faculty of Energy and Fuels

Abstract: Computational Fluid Dynamics (CFD) is currently the most popular method of solving thermal and fluid flow problems among others in environmental issues, mining (ventilation) and energy. These methods are used both in scientific research and in design and optimisation of industrial devices. Based on numerical simulation, scientists, created new models and designed new devices, as well as a new scientific hypothesis which are confirmed or not. Due to the unusually rapid development of computational algorithms and computational burden, it is possible to solve almost any thermal-flow problems, and the universality of computer modelling cause that more and more research studies to be often replaced by time-consuming and expensive experimental measurements. However, consciously using computer modelling as a key research and engineering tool, the question about the accuracy and reliability of the results of numerical calculations becomes extremely important. In the past, several scientific studies were carried out regarding the estimation of the accuracy of numerical calculations mainly based on verification and validation of results. However, at present, there is still no formalised methodology to validate this type of calculations which would increase the reliability of the obtained results. This research issue addresses the development of the methodology for the verification of numerical calculations for selected thermal and fluid flows problems in the field of energy. Based on the available literature knowledge as well as computer simulations and experimental measurements, a formalised methodology for numerical calculations will be proposed, so that the results obtained as a consequence of computer modelling become really reliable.

Research facilities: Our Division has a good reputation in computer modelling in the field of Computational Fluid Mechanic (CFD) as well as fully equipped thermal and fluid flow laboratories. We have many years of experience in CFD numerical analysis and thermal-flow measurements. In our resources, we have self-build and best available commercial numerical codes for thermal and fluid flow calculations. We have the most modern C ++ / C # and Fortran Intel compilers/optimisers with libraries oriented towards parallel and large scale calculations. We have our own 128 processor computing cluster, several HPC high-performance computing servers, including GPU-TESLA servers. In the AGH resources, there is also Cyfronet with the Prometeusz supercomputer for which we have permanent access. Experimental laboratories have ultramodern measuring equipment - Stereoscopic PIV (Digital image anemometry) and LIF (laser fluorescence induced) enabling three-dimensional measurement of the velocity field and temperature simultaneously in the entire tested measurement plane.

40. Novel catalysts for plasma-assisted tri-reforming of methane

Supervisor: prof. nadzw. dr hab. Monika Motak

Second supervisor: prof. Paolo Tosi

Faculty of Energy and Fuels and University of Trento (UNITN) Italy

Abstract: Chemical processing of CO2 treats this compound not as a harmful pollutant but as a source of carbon and may thus lead to the added-value products. The subject of PhD research concerns plasma-assisted tri-reforming of CO2, the latter either separated from flue gases from power stations or without its separation. Thermodynamics studies published in literature showed that the process is feasible and may lead to high conversion of CO2. There are, however, very few experimental studies of catalysts appropriate for the process. Additionally, as two of three main reactions are highly endothermal, considerable amounts of energy are required. Plasma assisted processes could thus improve the energy balance. The use of a plasma coupled with catalysts is a totally new approach to Tri-reforming, which has not yet been considered. The planned milestones of the research are: (i) preparation and modification of novel catalysts, basing on layered materials containing Ni as active component, (ii) characterization of the obtained catalysts (texture, structure, redox and basic properties), (iii)the determination of plasma-assisted catalytic activity, selectivity and stability, and (iv) the study of the influence of promoters on activity, selectivity and stability. Two types of CO2-containing mixtures will be taken into account - separated from coal- or gas-fired power stations via (i) amine method, or (ii) adsorption method.

41. Efficient catalysts preparation for plasma-assisted CO2 methanation

Supervisor: prof. nadzw. dr hab. Monika Motak

Auxiliary supervisor: dr Frederico Azzolina-Jury

Faculty of Energy and Fuels and CNRS -LCS (Normandie Université) France

Abstract: Chemical processing of CO2 may not only result in the production of important chemicals, but also be applied to store energy. One of such processes is CO2 methanation. Hydrogen for the reaction may be obtained from water electrolysis using off-peak, renewable or nuclear energy. The subject of this work will be to study the reaction mechanism on new catalysts based on layered materials, such as hydrotalcites, clays etc. Hydrotalcites are especially interesting as their basicity and redox properties may be tailored through appropriate choice of preparation methods and elemental composition. Additionally, their thermal processing leads to homogenous mixture of nano-oxides with increased interaction of active material (in this case Ni) with MgO and alumina, resulting in improved stability. Hydrotalcites containing Ni, Mg and Al with varying molar ratios and promoters will be prepared by different procedures and characterized by XRD, FTIR, UV-VIS, TPR and TPD-CO2.

The planned milestones of the research are: (i) Preparation, modification and characterization (texture, structure, redox and basic properties) of novel catalysts, basing on layered materials containing Ni as active component, (ii) Determination of plasma-assisted catalytic activity, selectivity and stability of the materials prepared in (i).

The PhD candidate will be trained in the methods of catalysts preparation and characterization at AGH and of plasma processes at CNRS (Caen). The PhD candidate will study the reaction mechanisms of the CO2 methanation reaction assisted by plasma in Caen, using the different materials prepared at AGH. The adsorbed species on the catalyst surface, both during adsorption or reactivity studies, will be followed by time-resolved Operando IR spectroscopy. LCS laboratory has already designed several plasma IR operando cells to this end. The catalyst wafer will be placed inside the reactor within discharge zone (plasma) perpendicularly to the IR beam. Both Glow-discharge and DBD discharge plasma assisted-cell/reactors were already conceived for mechanistic studies.

43. Using of heat accumulation based on PCM in power industry

Supervisor: dr hab. inż. Łukasz Mika, prof. AGH

Auxiliary supervisor: dr inż. Karol Sztekler

Faculty of Energy and Fuels and CNRS -LCS (Normandie Université) France

Abstract: Heat accumulation, and in particular heat accumulation in phase change materials (PCM) will become more and more important due to the growing global energy consumption and the need for rational energy management. Magazines (PCM) allow primarily for a more efficient use of energy, especially energy from renewable sources and waste energy, whose production capacity does not always coincide with the demand. The use of heat storage facilities with PCM in conventional power plants or combined heat and power plants increases the flexibility of these facilities and reduces the consumption of fossil fuels. Decreasing the consumption of fossil fuels the emission of harmful substances to the environment is reduced. They are also useful in distributed energy and cogeneration systems. The use of heat accumulators with phase change materials in construction reduces temperature fluctuations in rooms, increasing thermal comfort. In addition to the listed, most popular applications, heat storage can be used for many other purposes, such as heat removal from both technological processes and individual devices, maintaining a constant temperature during food transport, blood and organs transport for medical purposes and maintaining a constant body temperature through placing materials that accumulate heat in clothing.

Research facilities: The Department of Thermal and Fluid Flow Mechines from Faculty of Energy and Fuels has access to the existing laboratory in the field of research of heat storage using PCM under the agreement of the AGH University of Science and Technology in Cracow and Innogy Polska SA (formerly RWE Polska SA) regarding the feasibility of research.

44. Increasing the energy efficiency of adsorption chiller

Supervisor: dr hab. inż. Łukasz Mika, prof. AGH

Auxiliary supervisor: dr inż. Karol Sztekler

Faculty of Energy and Fuels and CNRS -LCS (Normandie Université) France

Abstract: One of the methods of using waste heat is the use of adsorption chillers. It is a technology that meets the challenges of saving energy resources as well as environmental protection. The main advantage of this type of cooling t is the lack of freon emissions to the environment and the minimum demand for electricity.

The adsorptive cooling devices use zero-emission refrigerants. This technology is very promising for improving energy efficiency, because it can use low temperature heat, at a much lower temperature than with the competitive absorption cooler technology. The trace cooling effect is noticeable at the temperature of the refrigerant supplying medium already at 45 ° C. In addition, this refrigeration device can also use solar power for power. Adsorptive cooling devices have a lot of advantages, but also disadvantages. The advantages mentioned above should include the simplicity of control, the lack of corrosion problems and the lack of vibration. The disadvantages include above all low refrigeration efficiency, high investment costs, discontinuity of operation or large dimensions and weight (as opposed to traditional refrigeration systems) and high design requirements. The research work within the doctoral thesis will be aimed at increasing the efficiency of the refrigeration refrigerator by optimizing the deposit and key structural elements of the device.

46. Numerical analysis of the phenomena occurring for two-phase impinging jets applied in the turbine blades cooling system

Supervisor: dr hab. inż. Elżbieta Fornalik-Wajs

Faculty of Energy and Fuels

Abstract: The proposed research topic “Numerical analysis of the phenomena occurring for two-phase impinging jets applied in the turbine blades cooling system” concerns the mass, momentum and energy transport processes occurring when the fluid jet hits the surface. Jet impingement is a method of the heat transfer enhancement existing in the various engineering systems. The idea is to generate small and fast-flow fluid jet which impinge on the heated (or cooled) surface, causing significantly higher heat transfer rates. Proposed topic includes also the analysis of two-phase flow (mist flow) and the phase change process, caused by the jet interaction with a surface of high temperature. An aim of the research is to analyze the heat transfer performance of this method applied in the turbine blade cooling system. At the first stage, the studies will concentrate on a construction of the numerical model considering the turbulent flow, interaction between the phases and of course phase-change phenomenon in the case of single jet and jets array impingement on the flat and curved surfaces. After the validation process, the model will be applied in the analysis of turbine blade cooling system.

47. Numerical analysis of time-depended energy and momentum transfer for the case of forced convection in the magnetic field

Supervisor: dr hab. inż. Elżbieta Fornalik-Wajs

Faculty of Energy and Fuels

Abstract: The proposed research topic concerns weakly magnetic fluid flow behavior in the presence of strong magnetic field. Fluids that are of para- or diamagnetic nature are relatively poorly examined, especially in the terms of forced convection. This gap creates a demand for the further research in this branch of science. It has already been stated that magnetic field influence on the weakly magnetic fluid flow in the phenomenon known as thermo-magnetic convection can be significant. This impact reveals itself in the form of flow structure and heat transfer modifications. The novelty in the proposed research topic is based on the extension to the transient analysis of the given phenomena, which is especially valuable in the terms of turbulent flows, where vortices of various size can appear.

The proposed research topic considers mainly numerical, but also experimental analysis (there is lack of them in the literature) of transient fluid flow of weakly magnetic substances (i.e. water, air). Mostly, the modified Graetz-Brinkman problem will be examined for the laminar and turbulent flows. The research concerning influence of boundary conditions, fluid magneto-thermal properties, thermal and magnetic conditions or coil and channel geometry on the forming flow structures and heat transfer is going to be conducted.

Research facilities: The topic will be realized at the Department of Fundamental Research in Energy Engineering (FREE), Faculty of Energy and Fuels, AGH University of Science and Technology.

Department of FREE is oriented on the analysis of transport processes regarding mass, energy and momentum in the case of various systems, it also initiated the analysis of natural and forced convection under the magnetic field in Poland. The numerical analysis of proposed topic will be based on the Ansys Fluent software and the resources of Computational Centre Cyfronet. Within the research scope, the experimental analysis is also considered. The FREE Department’s laboratory possesses laboratory infrastructure, which enables conduction of the experimental research. It should be mentioned that Laboratory of High Magnetic Field is equipped with the superconducting magnet, able to generate the magnetic field of magnetic induction up to 10 T. With this unit it is possible to change the magnetic field space orientation and its relation to the gravity, what will broadened the range of analyzed parameters. It should be emphasized that in the Department of FREE, the Candidate will get support regarding the knowledge and experiences within the research area, what in connection with the laboratory equipment and Computational Center will be the base for a realization of the topic.

Supervisor: dr hab. Katarzyna Zarębska, prof. AGH

Auxiliary supervisor: dr inż. Paweł Baran

Faculty of Energy and Fuels

Abstract: Expansion of hard coal accompanying the sorption of mine gases (methane and carbon dioxide) is an issue known in the literature. The conducted research is aimed at determining sorption-dilatometric interdependence, which is important, among others, from the point of view of exploitation of coal seams. Despite many years of research on this subject, there are many discrepancies in the results obtained. The high heterogeneity of the carbon rock makes it difficult to generalize this phenomenon based on the model. A significant number of scientific reports concern research in the isothermal system. However, there is a gap in the case of tests in the coal-gas mixture system (CO2 + CH4) under varying pressure and temperature conditions. Competitive sorption of methane and carbon dioxide in relation to volume changes is not described in the literature. The enrichment of current knowledge about test results in such a system is important from the point of view of safe coal exploitation in mines (extending knowledge about rock and gas outbursts) exploitation of coal bed methane with CO2 or direct carbon sequestration in unexploited deposits.

Research facilities: The Department has a unique apparatus for adsorption measurements in the low and high pressure range. Original equipment is also available for simultaneous sorption-dilatometric measurements. The staff of the Department have many years of experience in conducting sorption research. This experience is confirmed by publications in renowned scientific journals in this field: International Journal of Coal Geology, Energy Fuels, Adsorption, Adsorption Science and Technology.

51. LCA analysis of the domestic power sector in the terms of circular economy

Supervisor: dr hab. Katarzyna Zarębska, prof. AGH

Faculty of Energy and Fuels

Abstract: The main task of LCA analysis (life cycle assessment) is to determine the potential impact of the analyzed product (e.g. goods, services) on the environment by collecting data related to the processes of production, use and disposal of the product. In Poland, at the end of 2017, the share of hard coal in electricity generation was 46.4%, and brown coal 30.6%. The biggest problem of the power industry is the emission of exhaust gases and the production of solid by-products called CCP (coal combustion products). Appropriate waste management, especially in the power sector, is an important element ensuring the efficient use of natural resources while minimizing the negative impact on the environment and human health. Circular economy proposes a model of management for a single process or for a whole technology that does not generate waste but reuses everything. The aim of the research issue will be to analyze the life cycle assessment (LCA) of the domestic energy sector in the context of the circular economy.

54. Research on mercury speciation in environmental and industrial samples

Supervisor: dr hab. inż. Mariusz Macherzyński

Auxiliary supervisor: dr inż. Jerzy Górecki

Department of Coal Chemistry and Environmental Sciences, Faculty of Energy and Fuels

Abstract: Currently, all energy producers using power plants burning solid fuels trying to reduce mercury emissions. Attempts to reduce mercury emissions require reliable measurements of mercury concentration and its forms (speciation) in flue gases and other combustion products. New analytical needs make it necessary to develop new analytical tools (measuring apparatus and procedures). Mercury emitted by industry, mainly in the form of Hg0, can turn into a form of Hg2+, which enters water reservoirs. In bottom sediments, Hg2+ can be further transformed (through bacteria) into a much more toxic form - methylmercury (MeHg+).

The proposed research is a holistically approach to the problem of mercury emission. As part of the research, it is planned: to create new and modify existing analytical tools, measurements of mercury speciation in flue gases (laboratory and industrial systems), studying the process of sorption and desorption of mercury forms (Hg0, Hg2+) on/from elements of measurement systems and materials for mercury removal from flue gases. Measuring methylmercury in biological samples (cooperation with the Pomeranian Medical University) and optimization of measurement systems are also planned. As a part of the existing cooperation with the Energy Research Center of the Technical University of Ostrava, joint industrial measurements are planned in the Czech Republic.

Research facilities: As a result of many years of dealing with issues of mercury emission and its environmental effects, the Department of Coal Chemistry and Environmental Sciences has a large apparatus base that enables the implementation of virtually any mercury-related project. The apparatus that will be used in the research: a mobile system for mercury speciation in flue gas, EMP-2 mercury detectors (gas samples), low-pressure Hg2+ calibrator, mercury analyzers (solid and liquid samples) MA-2 and MA-3000 (Nippon Instrument Corporation), mercury detector Tekran 2500, HP 5890 II gas chromatograph, laboratory flue gas generator, thermal chamber for testing mercury removal materials, semi-automated Tenax-CG-AFS system for determination of MeHg in biological samples. In addition to the mentioned devices, the Mercury Analytical Laboratory has full, basic facilities for the sample preparation like lyophilizer, balances, mineralization units, centrifuges, ovens, etc.

Supervisor: dr hab. inż. Mariusz Macherzyński

Auxiliary supervisor: dr inż. Wojciech Zając

Department of Coal Chemistry and Environmental Sciences, Faculty of Energy and Fuels

Abstract: Ecological requirements cause that in modern installations the composition of process gases is strictly controlled, both during self-cleaning and during purification processes provided by the technology. The aim of research is to simulate and describe the mass exchange processes occurring between exhaust gases of various origin generated in the laboratory, and sorbents and ashes acting as adsorbents, which will be added to the sorption system. The measurements will be conducted under different conditions: temperature, flow, flue gas contact time with the solid phase. The subject of interest will be primarily heavy metals and their volatile forms occurring in the exhaust and the main components of waste gases. The investigated processes will be quantified by chemical analysis of the composition of ashes and sorbents (leaching tests, sequential extraction or waste mineralization) as well as on-line analysis of the composition of the treated gases. To carry out these tasks, it will be necessary to construct additional research reactors simulating different ways of contact of exhaust gases with ashes: fixed beds, moving (fluidizing) beds, entrained flow reactors. The methods of on-line measurement of gaseous components have to be modified, with the possibility of taking gas samples for further spectrometric analyzes.

Research facilities: DoCC&ES has facilities to perform and develop planned research both in the field of chemical analytics and sorption experiments. A part of DoCC&ES is the Mercury Research Laboratory, which is equipped in a measuring system of mercury removal from coal fumes (the station is currently equipped with a flue gas generator, bag filter, thermostatic chamber with sorption reactors and two gas mercury analyzers and flue gas conditioners). Additional components are sets of aspirators with scrubbers and a gas analyzer. This position will be developed as part of the presented research topic. DoCC&ES also has mercury analyzers in solid and liquid samples, a UV-Vis spectroscope, a flame photometer and a whole range of chromatographic stands (gas, liquid, IC). As part of didactic laboratories at the Laboratory of Environmental Protection and Radiochemistry, the AGH UST Energy Center scientists will be able to perform analysis of anions and cations and elementary analysis using a new generation of spectrometer with sample atomization in nitrogen plasma (MP-AES), in filtrates, extracts and digested samples.

Abstract: Within the framework of PhD thesis, it is planned to develop the methods for the preparation and shaping of the catalyst samples with various compositions, made in cooperation with AGH, and to test investigate them in a laboratory plant in the temperature range of 200-450 ° C, using the stream of real tail gases from the nitric acid plant. Based on the results obtained, the most active catalyst will be selected, for which in the stage the attempts will be made to scale-up its manufacturing process - from laboratory to the pilot scale. This pilot batch of the catalyst (with the suitable composition and properties) will be tested in the SCR reactor in the nitric acid pilot plant. As part of the doctoral thesis, the preparation of the catalysts samples will be performed, and their characterisation before and after the catalytic tests, with particular reference to the structural (XRD), textural and surface changes (SEM, low temperature nitrogen sorption, XPS). The activity, selectivity and stability of catalysts samples will also be investigated. On the basis of the obtained results, simulation calculations in the conditions of industrial installations will be made. The potential area of the application of the developed catalyst for the selective reduction of NOx are new and existing nitric acid plants. The implementation of the catalyst will not require the expensive modifications of the installation. In most nitric acid plants, it will be possible to install it in an existing reactor for the selective catalytic reduction of NOx from the tail gases.

Research facilities: The research team of the Department of Fuel Technology, Faculty of Energy and Fuels at the AGH University of Science and Technology has an extensive knowledge and many years of experience in the research of catalysts for SCR process in the laboratory scale.

57. The concept and design of revitalization of the Carpathian oil reservoirs through cyclical gas injection

Supervisor: dr hab. inż. Czesław Rybicki, prof. nadzw. AGH

Auxiliary supervisor: dr hab. inż. Jacek Blicharski

Faculty of Drilling, Oil and Gas

Abstract: The aim of the work is to develop a concept and prepare a project for the revitalization of oil reservoirs in the final study of exploitation through cyclic injection of gas to reduce its viscosity and thus increase its mobility. As a result, a much higher degree of depletion should be obtained. An important feature of this solution is the detailed geological analysis of the depleted oil reservoirs from the Carpathian area and then the current operation and adjustment of the gas injection volume will be restored. The analysis of the injected gas will take into account the properties of various gases such as: carbon dioxide, nitrogen and methane. The algorithms developed during the PhD course will enable the development of several variants of cyclic gas injection into a given oil field. The first stage of work will be the selection of the oil field or reservoir, the assessment of its drilling status, geological conditions as well as the feasibility of possibly new wells. In the next stage, the existing hydrodynamic models will be calibrated to the conditions of the given reservoir. The problem here may be the thinness of data due to the fact that these reservoirs often exploit oil for a period of several or even several dozen years. At various times, data was recorded in various ways. Current computer techniques allow you to obtain interesting information based on a slim database. It will be an ambitious challenge that will be presented to the future graduate. After selecting the reservoir, the next step will be to perform simulation calculations of the process of mutual displacement of two phases with the simultaneous analysis of such processes as: mixing, molecular diffusion, hydrodynamic dispersion and phase changes. The effect of these works is to prepare algorithms that will allow for optimal adjustment of the gas injection parameters to the oil field. The novelty of the work will be the development of cyclic technology rather than the continuous injection of gas into the oil field.

Research facilities: The Department of Gas Engineering has a wide laboratory base and experience in conducting research in the field of gas technologies. The experience gained comes from the implementation of research grants and work carried out on behalf of the gas sector companies.
