Nitrogen gas is an industrial gas produced using air separation by mechanical means by taking atmospheric air (the air that you are breathing - 78% nitrogen & 20.9% oxygen), pressurising it in an air compressor and then separating it with either a membrane or PSA (pressure swing adsorption) generator. Nitrogen can be supplied by high pressure nitrogen cylinders; dewars of liquid nitrogen; or bulk liquid nitrogen or a nitrogen generator.
Don't buy nitrogen - make it on-site!
Nitrogen Gas Generation has a wide variety of applications, including
- Serving as an inert replacement for air where oxidation is undesirable:
- To preserve the freshness of packaged or bulk foods (by delaying rancidity and other forms of oxidative damage) - potato chips, nuts, snack foods and packaged salads.
-To preserve the freshness of wine (by delaying rancidity and other forms of oxidative damage)
-On top of liquid explosives as a safety measure - paints and solvents
- The production of electronic parts such as transistors, diodes and integrated circuits (prevents oxygen and moisture)
-Dried and pressurised, as a dielectric gas for high voltage equipment
- Use in military aircraft fuel systems to reduce fire hazard.
