Abstract :

In petrochemical process, catalytic cracking of naphtha (NCC) process requires extremely high energy consumption for separation of ethylene from ethane or propylene from propane mixtures by low-temperature distillation. Membranebased gas separation enables these separation processes to be low-energy consuming and environment friendly, if high olefin selective membrane materials. Facilitated transport membranes (FTM) have been known to show very high olefin selectivity over paraffin. This study is aimed to develop the membrane materials and show their separation properties for propylene and propane. We prepared FTM module using PVP/AgBF4/TCNQ composite membrane on top of hollow fiber membrane. Pure gases and mixed gas permeation test were performed in various operational conditions. 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. The FTM showed high propylene/propane selectivity and propylene permeabilities. It is predicted that one-stage or two-stage membrane process provides over 99.5% of propylene at permeate side at high propylene recovery from a binary gas mixture of 95 vol% C3H6/5 vol% C3H8 supplied as a feed gas. The results showed FT membranes could be effectively used in C3 separation process instead of typical NCC (Naphtha Cracking Center) C3 splitter.
