    Assessment of the potential for CO2 capture using post-combustion methods
    (Wydawnictwa AGH, 2023) Kuś, Tomasz; Subramanian, Navaneethan; Madejski, Paweł; Karch, Michał
    The combustion of fossil fuels in the process of generating electricity causes the emission of carbon dioxide, which is considered the main anthropogenic reason for global warming. The paper’s subject is to assess the potential for $CO_{2}$ capture using post-combustion methods. Post-combustion methods such as chemical absorption, physical separation, membrane separation, and chemical looping, are described. The thermodynamic modeling of a coal-fired supercritical power plant integrated with a post-combustion carbon capture installation using the solvent method is performed. The results obtained from the model are used to investigate the impact of the power plant when carbon capture is performed.

    Ocena możliwości wychwytu CO2 metodami post-combustion
    (Wydawnictwa AGH, 2023) Kuś, Tomasz; Subramanian, Navaneethan; Madejski, Paweł; Karch, Michał
    Spalanie paliw kopalnych w procesie wytwarzania energii elektrycznej powoduje emisję dwutlenku węgla, który uważany jest za główną antropogeniczną przyczynę globalnego ocieplenia. Tematem pracy jest ocena możliwości wychwytu $CO_{2}$ metodami post-combustion. Scharakteryzowano główne rodzaje metod post-combustion, takie jak: absorpcja chemiczna, separacja fizyczna, separacja membranowa oraz pętla chemiczna. Przeprowadzono termodynamiczną analizę pracy nadkrytycznego bloku energetycznego zasilanego węglem i wyposażonego w instalację wychwytu $CO_{2}$ metodą rozpuszczalnikową. Bazując na wynikach modelowania, oceniony został wpływ zastosowania technologii aminowej na sprawność elektrowni oraz emisję $CO_{2}$.

    The research aims to comprehensively analyse Combined Cycle Gas Turbine (CCGT) power plants using thermodynamic modelling to develop high-efficiency and low-emission large-scale gas plants. It focuses on identifying fuel properties that enable the transition to carbon-free CCGT operation with CO2-neutral fuels. This achieved by using a mixture of gaseous fuels and syngas from sewage sludge, which is a biomass. Integrating syngas blends with fossil fuels and Post¬combustion Carbon Capture and Storage (PCCS) using solvent method creates potential for zero or negative CO2 emissions. The study evaluates fuel properties, various mixtures, and achievable CO2 capture levels. A model a large-scale CCGT power plant with CO2 capture is developed, considering critical components and inputs from thermodynamic analysis. Results based on the comprehensive analysis shows various fuel properties in gas-fired power plants to enhance combustion conditions using different gas fuels, impacts on the integration an operation of CCS installation in CCGT plant with the highest efficiency of CO2 emission reduction. The assessment confirms the system’s feasibility and economic viability
