Nitrogen Uses in Industry: Applications and Benefits


Nitrogen, an inert gas that makes up about 78% of Earth’s atmosphere, plays a crucial role in various industrial applications. Its unique properties make it invaluable across multiple sectors, from food processing to electronics manufacturing. nexAir, with its expert KnowHow™, has been at the forefront of supplying high-purity nitrogen and developing innovative applications for this versatile gas. Let’s explore the diverse uses of nitrogen in industry and its benefits to various processes.

Food and Beverage Industry

Nitrogen is a game-changer for preservation and packaging in the food and beverage sector. It’s used in modified atmosphere packaging (MAP) to displace oxygen, significantly extending the shelf life of packaged foods. By creating an inert environment, nitrogen prevents oxidation and inhibits the growth of aerobic microorganisms that cause spoilage.

Nitrogen is also used in the production of frozen foods. Flash freezing with liquid nitrogen helps maintain food quality by forming smaller ice crystals, which cause less damage to cell structures. This results in better texture and flavor retention upon thawing.

In beverage production, nitrogen is used for pressurizing and dispensing draft beer, creating the signature creamy head in nitro brews. It’s also used in wine-making to prevent oxidation during the bottling process.

Chemical and Petroleum Industries

The chemical industry relies heavily on nitrogen for various processes. It’s used to create an inert atmosphere in reactors, preventing unwanted oxidation or combustion. This is particularly important in the production of sensitive chemicals and pharmaceuticals.

In the petroleum industry, nitrogen is used for enhanced oil recovery (EOR). By injecting nitrogen into oil reservoirs, pressure is maintained, helping to extract more oil from the wells. Nitrogen is also used to purge pipelines and storage tanks, ensuring safety during maintenance operations.

Electronics Manufacturing

The electronics industry depends on ultra-high purity nitrogen to create clean, controlled environments for semiconductor manufacturing. Nitrogen is used to purge moisture and oxygen from production areas, preventing oxidation and contamination of sensitive components. It’s also used in soldering processes to improve the quality of connections by preventing oxidation.

Metal Processing and Fabrication

In metal processing, nitrogen plays a vital role in heat-treating operations. It’s used to create controlled atmospheres in furnaces, preventing oxidation and decarburization of metals during heating. This results in improved surface quality and mechanical properties of the treated metals.

Laser-cutting operations often use nitrogen as an assist gas. It provides a clean, oxide-free cut edge on materials like stainless steel, resulting in high-quality finished products that require minimal post-processing.

Healthcare and Pharmaceuticals

The healthcare sector uses nitrogen in various applications, from cryogenic storage of biological samples to the production of liquid nitrogen for dermatological treatments. In pharmaceutical manufacturing, nitrogen is used to create inert atmospheres for producing and packaging sensitive drugs, ensuring product stability and extending shelf life.

Tire Inflation and Automotive Industry

Many automotive manufacturers and racing teams use nitrogen for tire inflation. Nitrogen maintains more consistent tire pressure under temperature fluctuations than compressed air, leading to better fuel efficiency and longevity.

Environmental and Safety Applications

Nitrogen finds applications in environmental protection and safety. It’s used in oil spill cleanup operations to create a barrier preventing oil spread. In fire suppression systems, nitrogen displaces oxygen, effectively extinguishing fires in enclosed spaces without leaving residue.

Benefits of Using Nitrogen in Industrial Processes

The widespread use of nitrogen across industries is due to several key benefits:

  1. Inert Nature: Nitrogen doesn’t react with most substances as an inert gas, making it ideal for creating non-reactive environments.
  2. Purity: High-purity nitrogen can be easily produced and maintained, crucial for sensitive applications.
  3. Cost-Effectiveness: Being abundant in the atmosphere, nitrogen is relatively inexpensive to produce in large quantities.
  4. Versatility: Its unique properties make nitrogen suitable for various applications, from cryogenic cooling to pressurization.
  5. Safety: Nitrogen is non-flammable and non-toxic, making it safer to handle compared to many other industrial gases.
