GAS SEPARATION MEMBRANE MODULE

A gas separation membrane module includes a center pipe; a plurality of separation membranes each having a feed surface and a permeate surface, the separation membranes arranged such that the feed surfaces face each other and the permeate surfaces face each other; a feed channel material arranged between the feed surfaces; and a permeate channel material arranged between the permeate surfaces, wherein the separation membranes, the feed channel material, and the permeate channel material are wound around the center pipe, an average pore size on a front surface and an average pore size on a back surface of the feed channel material are each 0.95 mm or less, and an average pore size on a front surface and an averaged pore size on a back surface of the permeate channel material are each 0.95 mm or less.
