Abstract
Disclosed is a process for sealing a hollow fiber membrane separation module into a case. The hollow fiber mambrane separation module is formed from a plurality of hollow fibers arranged in a bundle surrounding a core and having tube sheets surrounding each end of the bundle which bind the hollow fibers together. The disclosed process simultaneous with such sealing creates first and second spaces overlying the ends of the plurality of hollow fibers. Such first and second spaces, in cooperation, permit the introduction and withdrawal of fluids through the lumens of the hollow fibers.
