    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.

    Abstract: The subject invention relates to a process for the selective separation of at least one component of a gaseous feedstream comprising passing the feedstream containing the component through a separation unit, the separation unit containing a porous membrane having a feed side and a permeate side, and a pore size of from about 10Angstroms to about 200Angstroms, and having disposed in the pores of the porous membrane a facilitator liquid comprising a carrier dissolved in a suitable solvent, including: a) dissolving the component in the facilitator liquid on the feed side of the porous membrane at the feed gas/membrane interface; b) forming a component-carrier complex; c) diffusing the complex to the permeate side of the porous membrane; and d) releasing the component from the carrier. The invention further relates to a membrane for the selective separation of at least one component of a gaseous feedstream comprising a porous membrane, having pores of from about 10Angstroms to about 200Angstroms, the pores containing a facilitator liquid having an affinity for the component to be selectively separated, the membrane being capable of operating at a transmembrane pressure of about 100psig to about 300psig. The subject invention also relates to use of the aboveidentified process and membrane for the separation of vapor phase olefins from olefin-containing feed streams.
