This study is aimed to separation propylene and propane using membrane process. Membrane-based gas separation enables a chemical process to be low-energy consuming, if high olefin selective membrane is developed. In this study, facilitated transport membrane (FTM) is used for propylene/ propane separation. We prepared FTM module using PVP/AgBF4/TCNQ composite membrane on top of hollow fiber membrane. We developed simulation program predicting the membrane separation properties under operation conditions. Separation properties of FTM module for propylene and propane were obtained from the simulation program based on the pure gas permeation data. Based on the these results, it is predicted that an one-stage membrane process provides 99.5% of propylene at permeate side from a binary gas mixture of 95 vol% C3H6/5 vol% C3H8 supplied as a feed gas.
