摘要： A gas separation membrane module has a vessel housing a hollow fiber element including a hollow fiber bundle consisting of a number of hollow fiber membranes (1) and a tube sheet (2) holding one end of the hollow fiber bundle. The interior of the vessel is partitioned by the tube sheet (2) into two spaces consisting of a raw gas chamber and a permeate gas chamber. A high-pressure mixed gas is fed into the raw gas chamber where gas separation is carried out. The gas separation membrane module has a configuration where during operation, the tube sheet (2) is supported by means of a perforated plate (8) in the vessel by a pressure from the mixed gas fed to maintain airtightness between the two spaces and when the tube sheet (2) receives a pressure in the reverse direction to that applied during the operation of the gas separation membrane module, the tube sheet (2) is forced to move within the vessel by the pressure in the reverse direction, thereby losing airtightness between the two spaces.

摘要： An asymmetric membrane is formed using a mixture of two or more different polymers including at least one type of polyimide. It is thereby possible to produce a gas separation membrane with low permeation resistance (a high permeation rate) for permeate gases passing through the porous layer of the membrane, which also maintains a practical level of mechanical strength of the membrane and has excellent water resistance and hot water resistance.
