Nitrogen

COMMERCIAL
GRADE – I (MAX. 2 PPM)
GRADE – II (MAX. 4 PPM)

Nitrogen (N2) constitutes 78.03% of the air, has a gaseous specific gravity of 0.967, and has a boiling point of -320.5°F (-195.8°C) at atmospheric pressure. It is colorless, odorless, and tasteless. Nitrogen is often used as an "inert" gas due to its non reactive nature with many materials. However, nitrogen can form certain compounds under the influence of chemicals, catalysts, or high temperature. Commercial nitrogen is produced by a variety of air separation processes, including cryogenic liquefaction and distillation, pressure swing adsorption (psa), and membrane separation.

Application:

Chemical Processing: To inert vessels and oxygen-sensitive chemicals, to propel liquids through pipelines.
Food: To extend shelf-life in packaged foods by preventing spoilage from oxidation, Moisture migration and insect infestation.
Petroleum Recovery and Refining: To blanket storage tanks and product loading/unloading, to purge pipelines.
Metal Production and Fabrication: To protect metals such as steel, copper and aluminum during annealing, carburizing and sintering operations in high temperature.
Electronics: To prevent Oxidation in the manufacture of semiconductors and printed circuits, To enhance solvent recovery systems by eliminating the use of chlorofluorocarbons for cleanup.
Glass Manufacturing: To cool furnace electrodes and prevent oxidation during manufacturing, To lower air temperatures for optimum cooling rates.
Research and Health Services: To freeze and preserve blood, tissue, semen and other biological specimens, To freeze and destroy diseased tissue in cryosurgery and dermatology, To precool or insulate Magnetic Resonance Imaging (MRI), Conserving the more costly helium.
