Nitrogen is used for a wide range of applications, including as atmospheric gas for semiconductor manufacturing and metal heat treatment, security and purge gas in chemical plants, for medical use, for frozen food production using cryogenic energy and for cryogenic grinding.

Applications

Semiconductors

High purity nitrogen is used in large quantities by the semiconductor industry as a purge or carrier gas as well as for blanketing equipment such as furnaces when not in production. Nitrogen is also used in the electronic industry for inerting of epitaxial reactors.

Food

Nitrogen is used in mixtures with carbon dioxide for modified atmosphere packaging (MAP) of food stuffs. Liquid nitrogen is used to freeze a wide variety of delicate food, such as hamburgers, strawberries, shrimps etc.

Metal Treating

Nitrogen is used extensively, either pure or, more com- only, in a mixture with a reducing gas such as hydrogen ‘ natural gas, to provide an oxygen free atmosphere during heat treatment of various metals.

Transportation

Nitrogen is used to fill tires to lower wear and limit the risks of blow-outs.

Scientific Research

Liquid nitrogen is used in the nuclear industry, for scientific research.

Biological

Liquid nitrogen is used to store biological materials like tissue, cells etc.

Medical

Liquid nitrogen is also used for cryo surgery. Liquid nitrogen is used in the area of superconductivity.
