Abstract: A device and method is disclosed for separating individual fluids (particularly gases) from a stream that contains more than one fluid. The separator device is made up of a bundle of hollow fibers fastened into a resin tubesheet at each end of the bundle. The fiber bundle is encased in a tube (casing) and in the center of the bundle is a perforated, distributor tube. Pressure load on one tubesheet is carried by a fixed head in contact with the tubesheet. At the other end of the separator device the tubesheet pressure load is counterbalanced by a floating head that utilizes pressure against its backside. Pressurized fluid directed into the distributor tube flows into the fiber bundle. The permeate fluids pass through the fiber walls and are carried out of the separator device through outlets at each end. The non-permeate fluids bypass the fibers and are carried out of the separator device through one or more outlets in the casing.

Abstract: A device and method is disclosed for separating individual fluids (particularly gases) from a stream that contains more than one fluid. The separator device is made up of a bundle of hollow fibers, which are fastened at each end into a resin tubesheet. The fiber bundle is enclosed in a casing and in the center of the bundle is a perforated, distributor tube. The pressure load on one tubesheet is carried by a movable flange in contact with the tubesheet. At the other end of the separator the pressure load is carried by a stationary flange that seats against the tubesheet. Pressurized fluid directed into the distributor tube flows into the fiber bundle. The permeate fluids pass through the fiber walls and are carried out of the separator through outlets at each end. The nonpermeate fluids bypass the fibers and are carried out of the separator through one or more outlets in the casing.
