ABSTRACT:
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 component in the effluent stream as necessary to obtain a predetermined concentration of the component in the effluent stream. A product stream having a relatively constant pressure and purity can be obtained by sensing a characteristic of a desired effluent stream, e.g., permeate, and performing a pressure adjustment on the other effluent stream, e.g., non-permeate.
