Membrane-based gas separation process is one of the next generations’ gas separation processes 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. The hollow fiber membranes used in this study shows CO2 permeance over 900 GPU (1 GPU = 10-6 cm³/cm²⋅sec⋅cmHg). Using the hollow fiber membranes and modules, we established a moveable CO2 separation system including pretreatment of flue gas and 3-stages of membrane cascade. The system was installed at the several on-site flue gas sources, and the performance of pilot plant operation will be presented in the presentation.
