후처리를 이용한 CO2 포집이 화력 발전설비 성능에 미치는 영향 해석

Abstract

Research and development efforts to reduce CO2 emission are in progress to cope with global warming. CO2 emission from fossil fuel fired power plants is a major greenhouse gas source and the post-combustion CO2 capture is considered as a short or medium term option to reduce CO2 emissions. In this study, the application of the post-combustion CO2 capture system, which is based on chemical absorption and stripping processes, to typical fossil fuel fired power plants was investigated. A coal fired plant and a natural gas fired combined cycle plant were selected. Performance of the MEA-based CO2 capture system combined with power plants was analyzed and overall plant performance including the energy consumption of the CO2 capture process was investigated.
