Abstract
The invention produces essentially pure nitrogen from air by an intermittent, automatic, and unattended process. Air is filtered, compressed and enters a nitrogen module containing a permeable membrane that selectively separates nitrogen from the air and discharges oxygen and other gases. Automated temperature and pressure controls allow the permeable membrane to separate air components. A discharge hose allows use of the nitrogen product for a variety of intermittent applications including vending for inflation of tires, filling portable nitrogen vessels, and use in manufacturing processes.
Claims12
A method for intermittent and automatic separating nitrogen from air comprising the steps of:
- (a) compressing and introducing said air into a module containing a permeable membrane means for separating said nitrogen from said air,
- (b) said permeable membrane means separating said nitrogen from said air permitting oxygen, carbon dioxide, moisture and other gases to pass through said membrane means while enriching said nitrogen to a desired purity by removing other air components,
- (c) providing a means for automatic controlling nitrogen pressure in said module,
- (d) providing means for automatic controlling temperature in said module,
- (e) providing conduit to contain said air and nitrogen in said apparatus when necessary until discharge and,
- (f) providing a means for automatically controlling and dispensing desired amounts of said nitrogen.
An apparatus for intermittent and automatic separating of nitrogen from air comprising:
- (a) an air compressor for introducing pressurized said air to a module containing a permeable membrane means for separating said nitrogen from said air,
- (b) said permeable membrane means for separating said nitrogen from said air permits oxygen, carbon dioxide, water vapor, and other gases to pass through said membrane means for separating while said nitrogen enriches to a desired purity by removal of other air components,
- (c) a means for automatic controlling nitrogen pressure in said module,
- (d) a means for automatic controlling temperature in said module,
- (e) conduit to contain said air and said nitrogen in said apparatus when necessary until discharge and,
- (f) a means for automatically controlling and dispensing desired amounts of said nitrogen.
