청구항

A process for the production of clean, dry air and nitrogen products rom feed air comprising: (a) passing wet feed air to the feed end of a membrane dryer unit capable of selectively permeating moisture present in said feed air, said membrane dryer unit having a high separation factor for water/air and being adapted for a countercurrent flow pattern between the feed air and the permeate gas, with permeate gas flowing on the low pressure permeate side thereof generally parallel to the flow of wet feed air on the feed side thereof, said membrane dryer unit...
