초록

Gas separation is one of the major chemical processes to manufacture petrochemicals and to recover the valuable chemicals from mixtures. However, the conventional gas separation processes requires enormous energy consumption and high costs. Membrane-based gas separation has been a major separation technology for various applications including natural gas sweetening, nitrogen generation, olefin/paraffin separation, CO2 capture, and biogas upgrading, etc. Most commercial gas separation membranes have been prepared using polymeric materials (e.g. cellulose acetate, polyimide, polyamideimide, polysulfone, and poly(dimethyl siloxane)(PDMS), etc.) as the form of hollow fiber membrane or thin film composite (TFC). In this presentation, polymeric gas separation membranes will be briefly introduced in terms of materials and fabrication methods.
