Abstract
A gas separation membrane module in which deformation of a tube sheet such as swelling and shrinkage can be prevented in gas separation. The gas separation membrane module includes a hollow fiber bundle provided by bundling multiple hollow fiber membranes, a module vessel in which the hollow fiber bundle is placed, and a tube sheet fixing the plurality of hollow fiber membranes at an end portion of hollow fiber bundle. The cross section of the tube sheet includes a hollow fiber membrane embedded portion in which the hollow fiber membranes are embedded and a solid portion in which no hollow fiber membrane is embedded, and the solid portion is located outside the hollow fiber membrane embedded portion. At least some of the hollow fiber membranes are wound with reinforcing fiber cloth at least within the hollow fiber membrane embedded portion.
