University Technology ISBN 978-952-265-520-2, 978-952-265-521-9 (PDF), ISSN 1456-4491 This thesis presents a one-dimensional, semi-empirical dynamic model simulation and CO2 capture. Reduction greenhouse emissions from fossil fuel power production requires rapid actions including development efficient sequestration technologies. The new technologies can be expedited by using modelling tools. Techno-economical evaluation processes done quickly cost-effectively with computational models before building expensive pilot plants. Post-combustion is developing which utilizes fluidized bed technology lime as sorbent. main objective this work was to analyse technological feasibility at different scales model. A one-dimensional applied process, simulating behaviour interconnected circulating reactors. incorporates fundamental mass energy balance solvers describing solid in chemical reactions occurring loop. In addition, combustion, heat transfer core-wall layer effects were modelled. framework successfully 30 kWth laboratory scale unit 1.7 MWth used design conceptual 250 industrial unit. Valuable information gathered small device. plant reactors effect fluidization on thermal balances system analysed. scale-up study provided practical an sized unit, selection particle size operability load scenarios.
