A process for producing a hollow fiber mass transfer module with a number of hollow fibers sealed into a housing is improved according to the invention with regard to the development of a desirable flow space in the surface area of the hollow fibers by the fact that a spacing material is applied to the outsides of the hollow fibers before their insertion into the housing (2). The thickness of the material is chosen to conform to the desired separation of the hollow fibers. The hollow fibers are arranged substantially parallel and inserted as a bundle into the housing and are fixed with the grout. The spacing material can have a layered or particulate and granular form. A hollow fiber mass transfer module produced by the process pursuant to the invention has hollow fibers suitably arranged at uniform mutual spacings.
A process for producing a hollow fiber mass transfer module, comprising introducing a plurality of parallel hollow fibers into a housing having an inner wall, sealing the ends of the fibers to one another and to the inner walls of the housing with sealing compound, said fibers being spread apart so that a first flow space is formed between the inner walls of the housing and the exterior of said hollow fibers and a second flow space is formed within the interior of the fibers determined by the interior of volume of the hollow fibers themselves which interior space is separated from said first flow space, wherein a spacing material is applied to the outside of the hollow fibers before their introduction into the housing the material having a thickness chosen to conform to the desired spacing of the hollow fibers passages, and wherein the hollow fibers are introduced as a bundle into the housing and are affixed thereto by a sealing compound.
