Abstract
Feed gas is introduced into the bores of a helically wound hollow fiber membrane cartridge containing hollow fibers of essentially uniform active lengths. Permeate gas flow is maintained countercurrent to the feed and raffinate gas entrance and exit axis, respectively, while the directional flow axis of permeate withdrawal can be at a substantial angle to the helically wound hollow fiber membrane surface. Complete radial mixing of the permeate stream on the outer, permeate side and essentially no axial mixing on either the permeate or the raffinate side of the hollow fiber membrane cartridge are maintained.
