Abstract

A membrane module for selective gas separation includes one or more separation units stacked one on the other, and at least one of interposed frame plates or stack-end frame plates. Each separation unit includes a support plate with a separation gas receiving structure and at least one corresponding gas separating membrane. The frame plates having a gas mixture flow chamber structure. Each separating unit and the frame plates contain (1) gas-mixture connecting channel structures in a first and a second side area formed by overlapping openings in the plates and extending in a stacking direction, which are in fluid connection with the gas mixture flow chamber structures; and (2) separation gas connection channel structures in a third and fourth side area, which are in fluid connection with the separation gas receiving structure or structures.
