HIGH PERFORMANCE FACILITATED TRANSPORT MEMBRANES FOR OLEFIN/PARAFFIN SEPARATIONS
A high performance facilitated transport membrane comprising a metal cation exchanged/chelated carboxylic acid functional group containing functional polyimide, a method of making this a membrane, and the use of this membrane for olefin/paraffin separations, particularly for propylene/propane and ethylene/ethane separations. The facilitated transport membrane has either an asymmetric integrally skinned membrane structure or a thin film composite membrane structure, wherein the top selective layer of the membrane comprises a metal cation exchanged/chelated carboxylic acid functional group containing functional polyimide.
