Abstract: A process for the separation of olefins from gaseous feed streams comprises the steps of passing a gaseous feed stream over one side of a facilitated liquid membrane which comprises a porous support member (15) and a liquid membrane comprising an aqueous solution containing a metal salt facilitator e.g. silver nitrate capable of coordinating with olefin gases and an alkyl carbonate e.g. ethylene carbonate co-solvent, and collecting the olefins on the other side of the membrane.
