ABSTRACT:
A process for the separation or concentration of olefinic hydrocarbons from mixtures of olefinic and paraffinic hydrocarbons uses a polyimide membrane, The process is well suited to separating propylene from propylene/propane mixtures. The novel method the membrane exhibits good resistance to plasticization by hydrocarbon components in the gas mixture under practical industrial process conditions.
