Investigation of the Cooling System of a Membrane-based Post-combustion Process

A rigorous heat exchanger design leads to a significant increase in the pressure drops at each heat exchanger and hence the pressure ratio required by the compression machines. The energy penalty of the membrane CCS system for 57% and 76% degrees of CO2 separation was increased from 4.7%-pts to 5.3%-pts and 7%-pts to 8.3%-pts, respectively, after implementing the rigorous heat exchanger design.
