Feasibility study on the carbonate looping process for post-combustion CO2 capture from coal-fired power plants

Worldwide innovations in the development of carbon capture technologies and the utilization of CO2

“…51 The regeneration of the calcium oxide can be enhanced under reduced pressure. 8,52 The released carbon dioxide stream can attain a high degree of purity.…”

“…Starting from a coal-fired base process with an efficiency of about 46%, the loss in efficiency is estimated to be #7.2% points (including CO 2 -compression and CO 2 -processing). [52][53][54][55] This method is also principally feasible as a retrofitting option for existing power plants.…”

The calcium looping cycle for CO2 capture from power generation, cement manufacture and hydrogen production

“…The carbonator is to be a CFB unit with a thermal duty up to 1 MWth operating at 650 C, and the calciner is to be a CFB unit with a thermal duty up to 1.5 MWth operating at 900 C. The plan is to demonstrate CO 2 capture from coal, biomass and / or RDF combustor (1 MWth) (Epple, 2009;Strohle et al, 2009a;.…”

CaO-based CO2 Capture Technology and Its Application in Power Plants

“…The carbonate looping process was integrated after the flue gas desulphurization unit of an existing power plant. The energy penalty is about 2.75%, much lower than that of other CO 2 capture technologies (Strohle et al, 2009). The retrofitted steam cycle which includes an air separation unit (ASU) and integrated CO 2 conditioning unit with interstage cooling increases the net generated power from 1052 MWe to 1533 MWe, resulting in an overall electric efficiency of 39.2% (Hawthorne et al, 2009).…”

“…The heat requirements for calcium looping cycle have been developed (Rodriguez et al, 2008). The carbonate looping processes of post-combustion CO 2 capture for coal-fired power plants have been studied (Strohle et al, 2009;Hawthorne et al, 2009). The carbonate looping process was integrated after the flue gas desulphurization unit of an existing power plant.…”
