ABSTRACT:
The subject invention relates to a membrane for the selective separation of at least one component of a gaseous feed stream comprising a porous membrane, having pores of from about 10 Angstroms to about 200 Angstroms, the pores containing a facilitator liquid having an affinity for the at least one component to be selectively separated, the membrane being capable of operating at a transmembrane pressure of about 100 psig to about 1000 psig, and the membrane comprising a polymer, a solvent, an alcohol non-solvent, and a viscosity enhancer and pore former.
