A gas separation membrane module is formed from a woven fabric of weft membrane hollow fibers and warp yarns. The membrane module includes an active hollow fiber region spanning the inner edges of the two tubesheets. The membrane module also includes two tubesheets formed by encapsulating membrane fiber on one or both ends. The tubesheet on the end includes a first sub-region adjacent the active fiber and a second sub-region extending from first sub-region to the outer face of the tubesheet. The spacing of the warp threads is relatively denser in the first sub-region than in the active region or the second sub-region.

A fast gas is recovered from a feed gas containing a fast gas and at least one slow gas using a gas separation membrane. A controller may control a control valve associated with a partial recycle of a permeate gas from the membrane for combining with the feed gas. A controller may control a control valve associated with the backpressure of a residue gas from the membrane.
