摘要： Module for gas separation that maintains moisture retention of a gas separation active layer at a uniform level has a composite hollow-fiber membrane configured as the interior of an exterior body and has a porous hollow-fiber support body and a gas separation active layer disposed on the surface of the hollow-fiber support body. The exterior body has a supply port and a discharge port for a first gas passing through the outer side of the composite hollow-fiber membrane, and a supply port and a discharge port for a second gas passing through the inner side of the composite hollow-fiber membrane. The first gas flows through a first space enclosed by the exterior body and the outer side of the composite hollow-fiber membrane and the second gas flows through a second space separated by the composite hollow-fiber membrane and the exterior body. The first space is filled with an absorbing solution.
