Title: Membrane module for selective gas separation

Abstract: A membrane module for selective gas separation includes one or moreseparation units stacked one on the other, and at least one of interposedframe plates or stack-end frame plates. Each separation unit includes asupport plate with a separation gas receiving structure and at least onecorresponding gas separating membrane. The frame plates having a gasmixture flow chamber structure. Each separating unit and the frame platescontain (1) gas-mixture connecting channel structures in a first and asecond side area formed by overlapping openings in the plates andextending in a stacking direction, which are in fluid connection with thegas mixture flow chamber structures; and (2) separation gas connectionchannel structures in a third and fourth side area, which are in fluidconnection with the separation gas receiving structure or structures.
