The invention is a fluid separation module with improved permeate flow characteristics. Such modules comprise a hollow fiber bundle, two tubesheets, a tubesheet support which encircles the bundle and is contacted with the outer edge of the inside of both tubesheets, a feed inlet, a permeate outlet, a non-permeate outlet, a core, and one or more baffles for channeling flow, wherein the baffles for channeling flow have one end embedded in the second tubesheet and the second end placed at a short distance from the first tubesheet, with the distance between the end of the baffles for channeling flow and the first tubesheet being sufficient to allow the permeate stream flowing along the baffles for channeling flow to flow to the permeate outlet.

A fluid separation module comprising: A. a plurality of hollow fiber membranes, wherein the hollow fiber membranes are arranged in a bundle form and are adapted for the separation of one or more fluids from one or more other fluids; B. a first tubesheet comprised of a thermoset or thermoplastic polymeric material at the first end of the bundle, arranged such that the hollow fiber membranes are embedded in the first tubesheet and communicate through the first tubesheet and are open on the opposite face of the first tubesheet; C. a second tubesheet comprised of a thermoset or thermoplastic polymeric material at the second end of the bundle opposite the first end, arranged such that the hollow fiber membranes are embedded in the second tubesheet and communicate through the second tubesheet and are open on the opposite face of the second tubesheet; D. a tubesheet support means which comprises a cylinder which encircles the bundle wherein a first end is bonded to or embedded in the first tubesheet, and a second end is bonded to or embedded in the second tubesheet; E. a feed inlet means adapted for introducing a feed mixture of fluids to be separated into the bores of the hollow fiber membranes by contacting the feed mixture with the hollow fiber membranes at the opposite face of the first tubesheet; F. a non-permeate outlet means adapted for removing the fluids, which do not permeate through the hollow fiber membranes, from the bore of the hollow fiber membranes at the opposite face of the second tubesheet; G. means for removing the fluids which permeate through the hollow fiber membranes from the vicinity of the hollow fiber membranes; H. a core, about which is arranged the hollow fiber membrane bundle, further arranged such that the core extends through and is bonded to the first tubesheet and the second tubesheet; I. a feed inlet region adjacent to the opposite face of the first tubesheet arranged to form a cavity into which the feed inlet means introduces the feed mixture, wherein the region is sealed such that fluid can only enter or leave the region through the feed inlet means or the hollow fiber membranes, and the feed inlet region is arranged to introduce the feed fluid mixture into the bores of the hollow fiber membranes; J. a non-permeate outlet region adjacent to the opposite face of the second tubesheet arranged to form a cavity into which the hollow fiber membranes introduce fluids which do not permeate the membrane, and from which the non-permeate outlet removes the non-permeating fluids from the module, wherein the non-permeate outlet region is sealed such that fluid can only enter or leave the region through the hollow fiber membranes or the non-permeate outlet means; K. one or more means for channeling flow, such means arranged to channel flow of permeate in the longitudinal direction parallel to the core toward the permeate outlet, wherein the means for channeling flow have one end embedded in the second tubesheet and the second end placed at a short distance from the first tubesheet, said distance between the end of the means for channeling flow and the first tubesheet being sufficient to allow the permeate stream flowing along the means for channeling flow to flow to the permeate outlet means; L. a casing means about the membrane module arranged to encase the entire hollow fiber membrane bundle and the two tubesheets; M. a means for forming a seal between the first tubesheet means and the casing such that fluid cannot communicate between the feed inlet region and the region between the two tubesheets which is outside of the hollow fibers; N. a means for forming a seal between the second tubesheet means and the casing such that gas cannot communicate between the non-permeate outlet region and the region between the two tubesheets which is outside of the hollow fibers; O. a first end capping means arranged for sealing the end of the casing means at the end of the casing means near the first tubesheet, thereby forming the feed inlet region; P. a second end capping means arranged for sealing the end of the casing means at the end of the casing means near the second tubesheet thereby forming the non-permeate outlet region; Q. a first attachment means arranged for attaching the first end capping means to the casing means; and R. a second attachment means arranged for attaching the second end capping means to the casing means.
