Abstract: A process for the selective separation of at least one component eg propylene of a gaseous feedstream comprises passing the feedstream containing the component through a separation unit (50), the separation unit (50) containing a porous membrane (53), eg in the form of a hollow fiber, the membrane (53) having a feed side and a permeate side, and a pore size of from about 10 Angstroms to about 200 Angstroms. Disposed in the pores of the porous membrane (53) is a facilitator liquid comprising a carrier eg silver nitrate dissolved in a suitable solvent. The process includes the steps of (a) dissolving the component in the facilitator liquid on the feed side of the porous membrane (53) at the feed gas/membrane interface; (b) forming a component-carrier complex; (c) diffusing the complex to the permeate side of the porous membrane (53): and (d) releasing the component from the carrier.
