Wydział Energetyki i PaliwItem type:Article, Access status: Open Access , Analysis and selection of CO₂ sources for CCS-EOR projects in oil fields clusters in Poland(Wydawnictwa AGH, 2018) Mikołajczak, Edyta; Kosowski, Piotr; Stopa, Jerzy; Wartak, JoannaArticle contains a detailed analysis and a preliminary selection of potential CO? emitters that can supply gas for CCS-EOR projects in oil fields clusters in Poland. The idea of $CO_2$ injection into clusters arises from the fact that oil reservoirs in Poland are relatively small, but very often located close together. Reservoirs grouping significantly increases the potential storage capacity and improves economic indicators. In addition, CCS-EOR projects combine $CO_2$ storage (CCS) with an increase in production from mature oil fields (EOR). The analysis was performed using a database of carbon dioxide emitters in Poland created by the National Centre for Emissions Management. This database contains a list of all registered $CO_2$ producers with annual emissions exceeding 1 Mg. On this basis, potential $CO_2$ sources for previously selected four clusters of oil reservoirs were chosen.Item type:Article, Access status: Open Access , Analysis and selection of CO₂ sources for CCS-EOR projects in oil fields clusters in Poland(Wydawnictwa AGH, 2017) Mikołajczak, Edyta; Kosowski, Piotr; Stopa, Jerzy; Wartak, JoannaArticle contains detailed analysis and preliminary selection of potential $CO_{2}$ emitters, who could be suppliers of gas for CCS-EOR projects in oil fields clusters in Poland.

Many countries have been actively trying to limit the greenhouse gases emission, mainly carbon dioxide, and implement the Carbon Capture and Storage (CCS) technology for years. One of the essential aspects of geological injection is constant monitoring of carbon dioxide, especially its pressure and temperature. Those parameters have an impact on viscosity, density and phase alterations during the flow. It is of vital importance to maintain the supercritical state of the fluid because it is the most efficient way of $CO_2$ storage. The negative impact of $CO_2$ on the properties of the cement slurry may disturb the exploitation of the well and create considerable hazard for the geological storage of carbon dioxide. Therefore, the cement slurry should be appropriately selected and the role of $CO_2$ in the development of technological properties of fresh and hardened cement slurry should be determined. The aim of this research is to select the most appropriate cement slurry composition exhibiting optimal properties with respect to the phase changes of carbon dioxide. The first part of the research consists in creating cement slurries of various compositions and investigating its thermal conductivity and sogginess under in-situ conditions. The second part concerns a possibility of utilization of fluidal ashes from combustion of lignite as a component of cement slurry.Item type:Thesis, Access status: Restricted , Ekologiczne aspekty podziemnego zgazowania węgla(Data obrony: 2021-02-02) Dobrowolski, Wojciech
Wydział Geologii, Geofizyki i Ochrony ŚrodowiskaItem type:Article, Access status: Open Access , Możliwości wdrażania czystych technologii węglowych w branży węgla brunatnego w Polsce(Wydawnictwa AGH, 2009) Kasztelewicz, Zbigniew; Polak, Krzysztof; Zajączkowski, MaciejThe climatic policy of EU is being gradually modified because of different understanding of the climate protection in member countries and because of the costs related to its implementation in particular states. However its goals are constant: reduction of greenhouse gases to the atmosphere, reducing the power consumption and increasing the participation of renewable energy sources. Independently of the final form of EU's energy-climate package the brown coal industry in Poland has to prepare for its consequences. Therefore it is necessary to implement so called »clean coal technologies« and expand the directions of brown coal usage. The article describes available and perspective coal technologies that - if implemented - would allow to decrease $CO_{2}$ emissions in Poland. The particular emphasis is put on: increasing the efficiency of power units running on brown coal, capture and storage of carbon dioxide as well as both underground and surface gasification of brown coal deposits. Future research directions over developing the most favorable in Polish conditions are shown, taking environmental, economical and technical considerations into account.Item type:Article, Access status: Open Access , Social acceptance for CO₂-EOR and CCS projects based on survey conducted in southeastern Poland(2015) Rychlicki, Stanisław; Kosowski, Piotr; Wartak, Joanna; Solecki, MarekThis paper presents the results of a survey on the public acceptance of $CO_{2}$-EOR and CCS methods. The survey has been conducted in southeastern Poland, on a sample of people living in the Carpathian region (Krosno, Jedlicze, Rymanów). Existing local reservoirs are taken into account of the possibility of enhanced oil recovery by injecting carbon dioxide. A survey has been done within the MUSE project to determine the impact of oil on the surrounding environment and the level of knowledge, perception and acceptance of CCS and $CO_{2}$-EOR methods. As appeared from the survey, public acceptance development of the oil industry in Poland is quite positive. Respondents recognize the need to use modern technologies such as $CO_{2}$-EOR and CCS to fulfill this task. A significant number of respondents show limited awareness (or lack of it) regarding these technologies. Public acceptance largely depends on the level of knowledge regarding the technology. One of the main directions of work undertaken prior to the implementation of industrial installations using technologies of $CO_{2}$-EOR and CCS should be gaining the acceptance of the local community.Item type:Thesis, Access status: Restricted , Symulacja procesu osuszania $CO_{2}$ z wykorzystaniem trójetylenoglikolu (TEG)(Data obrony: 2021-03-15) Protsiv, Mykola

In recent years, the method GCS (Geological Carbon Storage), injecting the $CO_{2}$ in a supercritical state underground for storage, is considered the most effective way to reduce greenhouse gas emissions. Saline aquifers are given special attention because of its huge amount of storage and, therefore, a deep saline aquifer is the best choice for the storage of $CO_{2}$. Exemplified by the well-explored Konary structure in the Polish Lowlands, results of assessments of $CO_{2}$ storage capacity are compared for three cases: (1) a simplified formula based on averaged geological and reservoir parameters and (2) a model of the structure based on averaged geological and reservoir parameters (homogeneous model) and (3) a model of the structure with more detailed geological data (including those on clay interbeds in the sandstone series of the reservoir horizon – heterogeneous model). This allows the estimation of how providing of details of geological and reservoir data, introduced into the model, can affect the ability of $CO_{2}$ migration within a reservoir horizon intended for $CO_{2}$ storage, and, consequently, also obtain a more accurate assessment of the capacity that the structure is capable of attaining.Item type:Article, Access status: Open Access , The future of carbon capture and storage technology: an innovative approach with digital twin(Wydawnictwa AGH, 2023) Bielka, PawełIn order to fight climate change, the EU has set a goal of achieving net-zero greenhouse gas emissions by 2050. To achieve carbon neutrality, greenhouse emissions from human activities should be at least 85% lower than in 1990. The remaining 15% can be achieved through additional measures such as increasing carbon capture and storage (CCS) and reducing emissions. CCS will facilitate the decarbonization of heavy industry, contribute to the emergence of a clean hydrogen economy, and aid in achieving net-zero emissions. As an emerging technology in the Industry 4.0, Digital Twin (DT) is gaining attention due to the possibilities arising from its application, such as precise process optimization in the design phase, quality control, monitoring, decision-making, and through comprehensive modeling of the physical world as a group of connected digital models. The introduction of digital technologies into the CCS sector has the potential to revolutionize the way $CO_{2}$ capture, transportation, and storage processes are carried out. This article aims to present the fundamental value of different modeling techniques, technologies enabling the creation of DT’s uncertainty quantification methods commonly used in Digital Twins, as well as the application of Digital Twin in CCS technology and the potential benefits it can bring, including increases efficiency and cost minimization. Additionally, the possibilities of using DS’s in improving process monitoring and forecasting were discussed which can contribute to better emission control and increases system effectiveness. Current research and projects utilizing this technology were also presented, including real-time modeling of fluid flow, $CO_{2}$ transport network optimization, and storage process improvement.Item type:Thesis, Access status: Restricted , Waste $Ca$ (Eggshells) natural materials for $CO_{2}$ capture(Data obrony: 2017-05-10) Trzepizur, Krzysztof
Wydział Energetyki i PaliwItem type:Article, Access status: Open Access , Wybrane aspekty techniczne rurociągowego transportu dwutlenku węgla(2012) Włodek, TomaszPozyskiwanie energii z węgla wiąże się z coraz większymi wyzwaniami w świetle światowych trendów związanych z ograniczeniem emisji dwutlenku węgla jako jednego z tzw. gazów cieplarnianych. Jednym ze sposobów redukcji emisji $CO_{2}$ jest wdrożenie technologii jego wychwytywania i geologicznego składowania. Podstawowym i integralnym etapem całego łańcucha technologii CCS łączącym wychwyt i składowanie jest transport dwutlenku węgla. Transport dużych ilości $CO_{2}$ (rzędu 2-10 MtCO$_{2}$/rok) na dużą odległość jest ekonomicznie uzasadniony tylko za pomocą rurociągów. Technicznie dwutlenek węgla może być transportowany w stanie nadkrytycznym oraz jako ciecz w warunkach ciśnienia nadkrytycznego. Położenie punktu krytycznego $CO_{2}$ (Pc = 7,38 MPa, Tc = 31,1 stopni Celsjusza) sugeruje przesył w zakresie bardzo wysokich ciśnień (8-15 MPa). Dodatkowo w przypadku utrzymywania stanu nadkrytycznego na całej długości rurociągu wymagane jest utrzymanie wysokiej temperatury, co jest bardzo energochłonne, wskazane jest także zastosowanie izolacji termicznej rurociągu, co dodatkowo zwiększa nakłady inwestycyjne. Natomiast opory przepływu transportowanego $CO_{2}$ w fazie ciekłej są znacznie mniejsze. W artykule przedstawione zostaną podstawowe założenia projektowe rurociągowego transportu $CO_{2}$, takich jak: wybór trasy, dobór średnicy rurociągu, wymagania materiałowe oraz koncepcje układów technologicznych. Przedstawione zostaną także wyniki symulacji przepływu strumienia dwutlenku węgla dla kilku odrębnych przypadków: stałego wydatku masowego, stałej średnicy rurociągu, zmiennego składu strumienia $CO_{2}$ oraz analizy zmian temperatury transportowanego dwutlenku węgla.
