Nowadays, the worsening environmental issue caused by CO₂ emission is greatly aggravated by human activity. Many CO₂ reduction technologies are under fast development. Among these, monoethanolamine (MEA) based CO₂ capture technology has been paid great attention. However, when connecting the CO₂ capture process with a coal-fired power plant, the huge energy and efficiency penalty caused by CO₂ capture has become a serious problem for its application. Thus, it is of great significance to reduce the related energy consumption. Based on an existing coal-fired power plant, this paper proposes a new way for the decarburized retrofitting of the coal-fired power plant, which helps to improve the overall efficiency of the power plant with less energy and efficiency penalty. The decarburized retrofitting scheme proposed will provide a new route for the CO₂ capture process in China.
