Integration of CO2 capture unit using blended MEA-AMP solution into coal-fired power plants

This study evaluated feasibility of using blended MEA and 2-amino-2-methyl-1-propanol (AMP) in the CO2 capture unit that is integrated into a supercritical coal-fired power plant. The evaluation was carried out by using the integrated power plant and gas absorption model developed at the University of Regina, Canada. Simulation results were presented in terms of energy requirement for solvent regeneration, sizes of absorber and regenerator, cost of CO2 capture and energy penalty. Conventional MEA process was also simulated and used as a benchmark for a comparison purpose. (C) 2008 Elsevier Ltd. All rights reserved.
