A CO 2 capture process using MEA (Monoethanolamine) scrubbing has been considered a leading technology in the early phase of the CCS (Carbon Capture & Storage) market due to its high CO 2 capture capacity and feasibility of use with existing power plant facilities. In spite of these advantages, this process has a disadvantage of requiring high energy for solvent regeneration in the stripper. For this reason, various improved solvents and process alternatives have been developed to reduce the solvent regeneration energy. This paper suggests an advanced MEA scrubbing process with a PSHE (phase separation heat exchanger) and shows its energy reduction effect using a commercial simulator. The main idea of the PSHE process is to reduce the reflux ratio of the stripper by sacrificing a part of the sensible heat recovery in the heat exchanger. In order to mitigate this sensible heat recovery loss, the PSHE process uses a phase separation heat exchanger. As a result, the PSHE process saves 123MJ/hr of condenser cooling energy while losing 51MJ/hr of sensible heat recovery in the phase separation heat exchanger. Consequently, the net energy reduction is 72MJ/hr, and the ton CO 2 capture energy decreases about 14%, from 3.31 GJ/ton CO 2 to 2.86 GJ/ton CO 2. © 2012 Elsevier B.V.
