First Claim
Patent Images
1. A process for transferring a fluid component between a shell-side fluid and a lumen-side fluid, said process comprising:
- (a) introducing a shell-side fluid into a fluid distribution element of a shell-less fluid contactor;
(b) introducing a lumen-side fluid into a lumen of at least one hollow fiber membrane external of the fluid distribution element; and
(c) discharging the shell-side fluid from the fluid distribution element into contact with the at least one hollow fiber membrane to effect diffusion of a fluid component between the shell-side fluid and the lumen-side fluid.

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.

5. A shell-less fluid contactor comprising:
-
(a) a fluid distribution element comprising at least one inlet for receiving a shell-side fluid, and at least one outlet for discharging the shell-side fluid; (b) at least one hollow fiber membrane being adapted for diffusion, said membrane having an internal surface defining a lumen and an external surface exposed to contact with the shell-side fluid, each said at least one hollow fiber membrane further comprising a first port in fluid communication with said lumen; and (c) a barrier for separating the first port of each said at least one hollow fiber membrane from the shell-side fluid. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
