Abstract

The feasibility of polymer membranes for the recovery of CO2 from flue gases of a power plant is examined. With a computer program based on the cross flow permeation model for membranes, several parameters are optimized to obtain the lowest specific CO2 mitigation costs. With gas separation membranes commercially available, the minimum attainable specific mitigation costs are calculated to be US$48 per tonne of CO2 avoided (at 50% CO2 purity, 75% CO2 recovery). When restrictions are posed to the purity of CO2 (95%) and the degree of CO2 recovery (90%), this figure is much higher: US$71 per tonne of CO2 avoided. Cost reduction possibilities and perspectives are discussed. Our analyses shows that membranes with a selectivity of at least 200 are required to make membranes a serious competitor of other separation techniques.
