Fluid separation module

Abstract

A fluid separation module to be mounted in a cylindrical shell and the method of mounting the same, the module including a bundle of hollow fiber membranes and a polymeric tube sheet, the tube sheet being positioned at one end of the bundle of hollow fiber membranes with the hollow fiber membranes extending through the tube sheet. A resilient sheet having the form of the slit tube surrounds the bundle of hollow fibers and is held in this configuration by a plurality of rings encircling the slit tube at spaced intervals thereon, the slit tube being secured to the tube sheet. The rings are moveably mounted on the slit tube in such a manner that, as the module is inserted in the shell, the rings can be manually slid to one end of the slit tube to allow the slit tube to expand into contact with the inner surface of the tubular shell and thereby allow the fiber bundle to open for improved flow of the fluid mixture through the bundle.
