Conventional Coal-Fired Power Plant an overview

Integration of post-combustion CO 2 capture (PCC) technology with conventional coal-fired power plants leads to a significant loss in power plant power production, ranging from 19.5% to 40% of their original output (Bert Metz et al., 2005; Thambimuthu et al., 2002; Page et al., 2009).This penalty is due to two main energy loads required for PCC operation, the liquid
