The carbon capture and storage (CCS) technology from industrial flue-gas is an important environmental issue these days. Membrane process can be competitive technology for its relatively small footprint and eco-friendly system. Many membrane modules with high selectivity and excellent flux have been developed so far. However, the high purity and recovery for CO2 capture can be achieved by optimization of operating conditions such as membrane area, feed/permeate pressure ratio and humidity of flue gas as well as membrane permeance or selectivity. In this study, we discuss the effect of operating parameters for high CO2 purity and recovery at permeate side. Using polymeric hollow fiber membrane, the single membrane process was tested to figure out the effect of feed flow rate, pressure ratio, membrane area and moisture content.
