(WO9312866-A1)      A nonlinear shaped fluid sepn. module with boreside or shellside feed comprises a bundle of hollow fibre membranes, the 1st end of which is embedded in, communicating through and/or open on the opposite face of a 1st tubesheet of thermoset/thermoplastic polymeric material and the 2nd end of which is sealed, embedded in the 1st tubesheet or embedded in a 2nd tubesheet, with the bundle protected from mechanical damage. An opt. tubesheet and bundle casing encloses the bundle and is opt. attached to the 1st tubesheet and the opt. 2nd tubesheet.    A feed inlet is adapted for the introduction of a feed mixt. of fluids to be sepd. into the membrane bores with a sealed feed inlet region adjacent to opposite face of 1st tubesheet forming a cavity. There is opt. a non-permeate outlet for removing fluids which do not permeate through membranes with an opt. non-permeate outlet region adjacent the opposite face of the opt. 2nd tubesheet forming a cavity. Fluids which permeate the membranes are removed via an exit opt. located near to 1st tubesheet to obtain countercurrent flow of permeate. There are opt. connections between 1st tubesheet and casing and between opt. 2nd tubesheet and casing to control movement of inlet feed and non-permeate. The 1st and 2nd tubesheets are capped and sealed to form the feed inlet region and non-permeate outlet region respectively.    USE/ADVANTAGE -   Has improved permeate flow characteristics and space/vol. requirements. Module is coiled, curved or bent to reduce space requirements without reducing fluid sepn. efficiency. Used for sepn. of gases.
