ABSTRACT:
The gas separator fixing structure of the present invention is characterized in that it is provided with a gas separator10having a gas separation membrane30formed on at least one surface of a tubular support31having a through hole7in axial direction and comprising porous ceramics, a cap-like metal member1and a ring-shaped metal member4are fixed to one and the other open end of the gas separator10through seal members, respectively, and seal members are gland packings11and12. A gas separating device can be provided in which there hardly occurs breakage of the tubular support constituting the gas separator10due to the thermal stress and there hardly occurs reduction of air-tightness between the gas separator10and the supporter supporting the gas separator caused by load of heat cycles, and besides which can be used even under the conditions of high temperatures.
