  • Shell-less hollow fiber membrane fluid contactor
    Patent number: 6149817
    Abstract: A shell-less fluid contactor and a process for transferring a fluid component between a shell-side fluid and a lumen-side fluid. The shell-side fluid is introduced through a fluid distribution tube and discharged from the tube into contact with a surrounding bundle of microporous hollow fiber membranes. A fluid component is transferred by diffusion, through the walls of the hollow fiber membranes, from the shell-side fluid to the lumen-side fluid. Multiple contactors can be combined into an assembly for multi-stage processing of fluids.
