Abstract
Post-combustion carbon capture is one of the feasible methods to reduce emission of carbon dioxide (CO2) from coal-fired power plants. This work proposes a hollow fiber based rapid temperature swing adsorption (RTSA) method for capturing CO2 from a typical 550 MW coal-fired power plant. The proposed RTSA approach can shorten the operating time and using low-grade energy for regeneration of adsorption elements. This work studies the impact of using low-grade steam extracted from a low-pressure turbine as the heating source of the dual column vacuum RTSA (DC-vRTSA). The DC-vRTSA at 120 °C-55 °C will reduce the efficiency of the coal-fired power plant by 8.2 % to 1.9 %. The lowest CO2 capture cost, 19.20 US dollars per tons of captured CO2, is located at 60 °C desorption temperature.
