A process and an apparatus are disclosed for controlling the concentration of a component in an effluent stream from a permeable membrane gas separation system. A gaseous feed stream is passed to the membrane system at a substantially constant flow and elevated pressure. Control is achieved by sensing a characteristic of an effluent stream that is indicative of the concentration of the component, i.e., permeate or non-permeate stream, and performing a pressure adjustment on the permeate stream or non-permeate stream, to vary the concentration of the comp...
In a permeable membrane gas separation process which comprises: (a) passing a gaseous feed stream comprising a component to a permeable membrane gas separation system at a substantially constant flow rate and elevated feed pressure, said feed pressure being equal to or higher than the pressure required to operate the permeable membrane gas separation system and said feed stream being subject to fluctuations in composition; and (b) recovering from said permeable membrane gas separation system, an effluent stream comprising a permeate stream or a non-perme...
