Nitrogenium is classified as inert gas. By volume, its share in the Earth atmosphere is the largest (over 78%). Liquefied nitrogen is produced by low-temperature air separation. Then, nitrogen gas is produced from liquefied nitrogen.

  • Gas under pressure
  • colorless
  • odorless
  • asphyxiating
  • slightly lighter than air.

Nitrogen has a wide range of applications in various industrial sectors. For example for:

  • creating an inert atmosphere during transportation and storage
  • metal processing under high-temperature conditions
  • preserving metal pipes
  • chromatography (in medicine)
  • research purposes
  • companies working with food products and beverages
  • metal processing in the metallurgical industry.

When transporting, pure nitrogen gas is classified as hazardous cargo. In its gaseous state, it can be transported by any land transport (automobile, rail, or water). Inert gas is transported in steel cylinders under pressure. All containers must meet strict GOST standards.

During transportation or storage, gas cylinders must not be heated, dropped, or subjected to any other impacts. Overheating or a heavy impact can pose an explosion risk.

Nitrogen is not harmful to the environment and ecology. It is non-toxic. However, inhaling large amounts of the substance can be life-threatening. When working with nitrogen, it is necessary to monitor the oxygen level in the surrounding space. It should not fall below 19%.

Pure nitrogen is dangerous when transporting

  • train
  • truck
