Nitrogen

Nitrogen is produced in large quantities at air separation plants which liquefy and subsequently distil air into nitrogen, Oxygen and usually Argon. If very high purity nitrogen is required the nitrogen produced may need to go through a secondary purification process. The lower range of nitrogen purities can also be produced with membrane techniques, and medium to high purities with pressure swing adsorption (PSA) techniques.

Nitrogen is used extensively in the chemical industry for blanketing, purging and pressure transfer of flammable chemicals. High-purity nitrogen is used extensively by the semiconductor industry as a purge or carrier gas, and to cover equipment such as furnaces when not in production. Nitrogen is a colorless, odorless, tasteless, non-toxic inert gas. Liquid nitrogen is colorless. The relative density of the gas at 21.1°C and 101.3kPa is 0.967. Nitrogen is not flammable. It can combine with some particularly active metals such as lithium and magnesium to form nitrides, and can also combine with hydrogen, oxygen and other elements at high temperatures. Nitrogen is a simple smothering agent.
