The impact of post-combustion carbon dioxide capture on the performance of a power plant is evaluated in this study. A model of a coal power plant with post-combustion temperature swing adsorption (TSA) CO2 capture using sorbent-loaded hollow fibers is presented. The study compares the resulting performance and cost of carbon capture with other adsorption-based technologies. The analysis of key parameters in the hollow fiber module operation reveals that electrical energy consumption for CO2 compression is a major parasitic load common to all absorption technologies.
The impact of post-combustion carbon dioxide capture on the performance of a power plant is evaluated. A model of a coal power plant with post-combustion temperature swing adsorption (TSA) CO2 capture using sorbent-loaded hollow fibers is presented. The resulting performance and cost of carbon capture are compared with those of other adsorption-based technologies. A parametric analysis of the performance of the power plant with respect to key parameters in the hollow fiber module operation is presented. It is found that electrical energy consumption for the compression of CO2 is a major parasitic load (PL) common to all absorption technologies and accounts for almost half of the total parasitic load. The effect of source temperature, flue gas (FG) fan, and coupling fluid pump flowrates on overall system performance is presented. The impacts of different carbon capture technologies on the same coal-fired power plant are compared. Hollow fiber modules had the lowest parasitic load on the power plant, followed by KS-2 based carbon capture.
