Membrane-based gas separation is one of the next generations’ gas separation technology for carbon capture and storage (CCS). Membrane process has the advantages of i) low energy consumption without a phase change during the separation, ii) small footprint and easy scale-up of membrane modules, and iii) clean process without any emission of harmful byproducts. However, the requirement of CO2 separation membrane for CCS has limited the application of gas separation membranes in the industrial field. Here, we demonstrate the strategies to approach to the current limitation by developing a high flux of polymeric hollow fiber membrane. The membrane performance in this work is 900 GPU (1 GPU = 10-6 cm3/cm2‧sec‧cmHg) of CO2 permeance. The CO2 capture pilot plant using multi-stage membrane processes at KDHC has been on-site tested.
