Abstract
A mixed gas-separating membrane module having a high separating efficiency includes a cylindrical container having a mixed gas-feed section, a non-permeated gas-delivery section, and a middle section; a bundle of a plurality of hollow fibers each extending through the middle section and each having an end portion opening to the mixed gas-feed section and an opposite end portion opening to the non-permeated gas-delivery section; a pair of a first disk supporting the hollow fiber end portion opening to the mixed gas-feed section and partitioning the middle section from the mixed gas-feed section, and a second disk supporting the opposite hollow fiber end portions opening to the non-permeated gas-delivery section and partitioning the middle section from the non-permeated gas-delivery section, the first and second disks supporting the hollow fibers so that the hollow fibers are spaced from each other, to leave a continuous space between the hollow fibers; and a cylindrical film member surrounding the hollow fiber bundle to such an extent that the continuous space formed between the hollow fibers is connected to a permeated gas-delivery outlet of the middle section, the middle section, …
