✦ Synopsis

This paper presents the techno-economic performance of 600 MW coal-fired power plant with and without MEA-based CO~2~ capture process, based on the operating data of an existing power plant. The simulation and analysis are based on ASPEN PLUS, with fully consideration of features of existing coal-fired power plants and the integration of CO~2~ capture process with steam cycle. The results show that, when adopting CO~2~ capture process, the plant efficiency will decrease significantly. And the cost for electricity will increase dramatically. Through further system integrated optimization, the efficiency fall from 40.28% to 29.61%, which is still tremendous but obviously better performance than before.
