摘要： PROBLEM TO BE SOLVED: To provide a method for degassing a liquid with a membrane contactor.SOLUTION: A liquid having a dissolved gas is introduced into a contactor which is connected to a vacuum source. The contactor 12 has a perforated core 32, a plurality of hollow fiber membranes 38, a tube sheet 40 affixing each end of the fibers, and a shell 42 having a liquid egress. The shell encloses the fibers, the tube sheet, and the core. Hollow fiber lumens are in fluid communication with the vacuum source. The liquid enters the contactor via the core's open end 34, radially exits the core, crosses over the membranes within the shell, and exits the contactor by the liquid egress 44. 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 1 ppb.
