Abstract:
A membrane module for selective gas separation, comprising:(A) one or more separation units, each separating unit comprising a support plate, a gas-receiving structure, and at least one gas-separation membrane;(B) frame plates connected to said one or more separation units and defining one or more gas-mixture flow chambers;(C) first gas-mixture connection openings disposed in a first side area, which overlap one another in a stacking direction, forming a first gas-mixture connecting channel structure;(D) second gas-mixture connection openings disposed in a second side area, which overlap one another in the stacking direction, forming a second gas-mixture connecting channel structure;(E) first separation-gas connection openings disposed in a third side area, which overlap one another in the stacking direction, forming a first separation-gas connecting channel structure; and(F) second separation-gas connection openings disposed in a fourth side area, which overlap one another in the stacking direction, forming a second separation-gas connection channel structure,wherein the first and second gas-mixture connection channel structures are configured to allow a gas mixture to be fed in parallel from the first gas-mixture connection channel structure to the second gas-mixture connection channel structure over an entire surface of the at least one gas-separation membrane facing the one or more gas-mixture flow chambers,wherein the first and second separation-gas connecting channel structures are in fluid connection with the gas-receiving structure,wherein each separation unit and the frame plates are rectangular and the first and second gas-mixture connection channel structures are situated at the two short rectangle sides and the first and second separation-gas connecting channel structures are situated at the two long rectangle sides.
