Gas separator fixing structure and gas separating device using the same

A gas separator fixing structure provided with a gas separator having a gas separation membrane formed on at least one surface of a tubular support having a through hole in axial direction and comprising porous ceramics, characterized in that ring-shaped metal mewbers are fixed to both open ends of the gas separator through seal members, respectively, and the seal members are gland packings.

A gas separating device comprising a gas separator fixing structure provided with a gas separator having a gas separation membrane formed on at least one surface of a tubular support having a through hole in axial direction and comprising porous ceramics, wherein a cap-like metal member and a ring-shaped metal member are compression-fixed to one and the other open end of the gas separator through seal members, respectively, and seal members are gland packings, and being provided with a pressure container, wherein the ring-shaped metal member is fixed to an inner surface of the pressure container.

A gas separating device comprising a gas separator fixing structure provided with a gas separator having a gas separation membrane formed on at least one surface of a tubular support having a through hole in axial direction and comprising ceramics, wherein the gas separator fixing structure is fixed in a container having an inlet, a first outlet and a second outlet,

• wherein a specific gas component in a gas to be treated which flows into the device from an inlet is allowed to permeate the gas separation membrane and to flow out from the first outlet, and a gas which does not permeate through the gas separation member is allowed to flow out from the second outlet, and
• wherein ring-shaped metal members are fixed to both open ends of the gas separator through seal members, respectively, and the seal members are gland packings.
