Nitrogen (N2) makes up the major portion of the earth’s atmosphere, accounting for 78.08% of total volume. It is a colourless, odourless, tasteless, non-toxic and almost totally inert gas. It can be an asphyxiant in high concentrations. Nitrogen is produced in high volumes at air separation plants. A second purification process may be necessary if very high purity levels are required. Membrane techniques can also be used to recover nitrogen in lower purities. Pressure swing adsorption (PSA) techniques are suited to medium-to-high purities.
Nitrogen produced by Linde Gas Vietnam’s Air Separation Plants reaches extremely high purity. It is directly supplied to customers through pipeline system or delivery fleet for various customer demand from 10 Nm3/hr to more than 1,000 Nm3/hr. We also provide On-site plant solutions for customer with high demand of Nitrogen.

Main applications of Nitrogen
There are various applications of Nitrogen in either daily life or industry. It is widely used in many industries, such as: stainless steel, food reservation & packaging, semiconductor and electronics, etc.
Nitrogen in gas form:
- One of the main applications of nitrogen is blanketing, purging and sparging in the food and chemical industries.
- Nitrogen is used in modified atmosphere packages (MAP) for foodstuffs.
- In the semiconductor industry, N2 is used in large quantities as a purge and carrier gas. In electronics, it acts as an inerting agent for epitaxial reactors.
- It is also useful as a carrier, zero and balancing gas in laboratory analysis
- Nitrogen is used for stainless steel production
- Other common applications include heat treatment, the production of ammonia, fire extinguishing in mines, tyre filling, shrink-fitting and cold traps.
Nitrogen in liquid form:
In liquid form, it is an agent to shock-freeze food, store biological material, perform cryosurgery and cryogenically grind plastics and rubbers, for instance,… Nitrogen used in food freezing helps to effectively shorten freezing time and preserve food’s quality and freshness.
