초록

This invention comprises an improved process for generating Nitrogen from air in which a vacuum is placed on the permeate side of a gas separation membrane, usually of the polysulfone type, resulting in highly enhanced flow rates and nitrogen purity sufficient for oil and gas pipeline repair use and for use in grain silos.

청구항

[ What is claimed is:] [1.] A process for producing nitrogen gas from air at an enhanced flow rate wherein the oxygen content of the produced gas is 8% or less using a membrane separator, the process comprising: (a) moving compressed air at a pressure from about 40 psig to about 120 psig into a membrane separator containing a plurality of hollow fiber membranes confined in a container, the separator being adapted to permit selectively the passage therethrough of oxygen, carbon dioxide and water vapor while restraining the passage of nitrogen; (b) applyin...
