Individual fluids (particularly gases) are separated from a stream that contains more than one fluid by passing through a separator device made up of a bundle of hollow fibers (11), which are fastened at each end into a resin tubesheet (16,19). The fiber bundle is enclosed in a casing (10) and in the center of the bundle is a perforated, distributor tube (12). The pressure load on one tubesheet (16) is carried by a movable flange (22) in contact with the tubesheet (16). At the other end of the separator the pressure load is carried by a stationary flange (28) that seats against the tubesheet (19). Pressurized fluid directed into the distributor tube (12) flows into the fiber bundle. The permeate fluids pass through the fiber walls and along the fibers into spaces (26a,31) between the tubesheets (16,19) and the respective flanges (22,28) and are carried out of the separator through outlets (34,35) at each end. The nonpermeate fluids bypass the fibers and are carried out of the separator through one or more outlets (33) in the casing (10). |
