Abstract
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.
