<p>The present invention is directed to degassing a liquid with a membrane contactor (12). A liquid having a dissolved gas is introduced into a contactor which is connected to a vacuum source. The contactor has a perforated core (32), a plurality of hollow fiber membranes (38), a tube sheet (40) affixing each end of said fibers, and a shell (42) having a liquid egress (44). The shell (42) encloses the fibers (38), the tube sheet (40), and the core (32). The hollow fiber lumens are in fluid communication with the vacuum source. Liquid enters the contactor (12) via the core's open end (34) radially exits the core, crosses over the membranes (38) within the shell (42), and exits the contactor (12) by the liquid egress (46). The dissolved gas thereby diffuses from the liquid across the membrane into the lumen. The liquid exiting may have a dissolved gas content to less than 1ppb.</p> |
