A hollow fiber membrane fluid separation device adapted for boreside feed comprising: A. a plurality of hollow fiber membranes, wherein the hollow fiber membranes are arranged in a bundle and are adapted for the separation of one or more fluids from one or more other fluids in a feed fluid mixture; B. a first tubesheet comprised of a thermoset or thermoplastic polymeric material located 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 located at the second end of the bundle opposite the first end of the bundle, 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 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; E. a casing means encasing the hollow fiber membrane bundle, the first and second tubesheets, and the core; F. a first end capping means arranged and adapted for sealing the first end of the casing means at the end of the casing means near the first tubesheet; G. a first attachment means arranged for attaching the first end capping means to the first end of the casing means; H. a feed inlet means adapted for introducing the feed fluid mixture to be separated into the bores of the hollow fiber membranes by contacting the feed fluid mixture with the open hollow fiber membranes at the opposite face of the first tubesheet; I. a feed inlet region defined by the first end capping means and the casing means located adjacent to the opposite face of the first tubesheet, wherein the feed inlet region is sealed such that fluid can only enter or leave the feed inlet 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 first means for forming a seal between the first tubesheet means and the casing means such that fluid cannot communicate between the feed inlet region and the region between the two tubesheets which is outside of the hollow fiber membranes; K. a second end capping means arranged and adapted for sealing the second end of the casing means at the end of the casing means near the second tubesheet; L. a second attachment means arranged for attaching the second end capping means to the second end of the casing means; M. a non-permeate outlet means adapted for removing fluid which does not permeate through the hollow fiber membranes from the bores of the hollow fiber membranes at the opposite face of the second tubesheet; N. a non-permeate outlet region defined by the second end capping means and the casing means located adjacent to the opposite face of the second tubesheet, wherein the non-permeate outlet region is sealed such that fluid which does not permeate the hollow fiber membranes can only enter or leave the non-permeate outlet region through the hollow fiber membranes or the non-permeate outlet means and the non-permeate outlet region is arranged to remove the fluid which does not permeate the hollow fiber membranes from the bores of the hollow fiber membranes; O. a second means for forming a seal between the second tubesheet means and the casing means such that fluid cannot communicate between the non-permeate outlet region and the region between the two tubesheets which is outside of the hollow fiber membranes; P. a permeate outlet means for removing fluid which permeates through the hollow fiber membranes from the region between the two tubesheets which is outside of the hollow fiber membranes; and Q. one or more means for channeling flow of fluid which permeates through the hollow fiber membranes to the region between the two tubesheets which is outside of the hollow fiber membranes, such means for channeling flow arranged to channel flow of fluid which permeates through the hollow fiber membranes in the longitudinal direction parallel to the core toward the permeate outlet means, wherein the means for channeling flow have one end embedded in or attached to the second tubesheet and the second end located at a distance from the first tubesheet, said distance between the second end of the means for channeling flow and the first tubesheet being sufficient to allow the fluid which permeates through the hollow fiber membranes and flows along the means for channeling flow to flow to the permeate outlet means.
