Uses & Applications for Nitrogen by Industry

– Food & Beverage

Nitrogen is a key cryogenic agent in cooling, chilling and food freezing. Immersion freezing in liquid nitrogen is the fastest freezing method known for producing Individually Quick Frozen (IQF) foods. Additionally, Nitrogen plays a key role in reducing spoilage, discoloration and off-flavors, providing strength to retail packaging.

  • Freezing & Chilling
  • Flour & Dough Cooling
  • Meat Mixing
  • Modified Atmosphere Packaging
– Healthcare

Nitrogen NF is used to freeze and preserve blood, tissue, and other biological specimens. Additionally, it is used to freeze and destroy diseased tissue in cryosurgery and dermatology. Using it to power medical devices is another application.

  • Medical Laboratory
  • Minimally Invasive Cryotherapy
  • Tissue Transport & Blood Platelet Preservation
– Pharmaceutical & Biotechnology

Nitrogen, in its gaseous form, is used for purging, pressure transferring, mixing and blanketing, which is a process for protecting from moisture intrusion, oxidation, degradation and contamination. Cryogenic liquid nitrogen is used to control the temperature in reactor cooling applications and to preserve biological samples.

  • Reactor Cooling
  • Lyophilization
  • VOC Treatment & Recovery
– Welding & Metal Fabrication

In stainless steel tube welding, nitrogen is used as a purge gas. It is also used as an assist gas for laser cutting, and enhances plasma cutting.

  • Cutting Processes
  • Welding Processes
– Aerospace & Aircraft

Nitrogen is a key gas used in the aerospace & aircraft industry It is used in high Reynolds number wind tunnels, heat treating furnaces and autoclaves to help create extremely strong and lightweight materials. Another application uses it as an assist gas for laser cutting applications.

  • Autoclave Inerting
  • Heat Treating
– Automotive & Transportation Equipment

Assembly plants use nitrogen in combination with other welding gases to weld auto parts, frames, mufflers and other components. Its value is its ability to provide the necessary atmosphere needed to produce strong welds with any material. An additional usage is as a safety component in airbags.

  • Heat Treating
  • Parts Manufacturing
– Chemicals

Nitrogen is used as a pressurizing gas that can help propel liquids through pipelines. Another application is using it to shield oxygen-sensitive materials from the air and to remove volatile organic chemicals from process streams.

  • Inerting
  • Nitrogen Stripping & Recovery
  • Reactor Cooling
  • VOC Treatment & Recovery
– Energy

Nitrogen is an inert industrial gas that is used as a blanketing agent to separate sensitive products and processes from air. It is also used as a purging agent in piping and equipment to prevent contamination.

  • Nitrogen Stripping & Recovery
  • VOC Treatment & Recovery
– Metal Production

A carrier and purge gas in steel production, nitrogen is used to prevent oxidation and is used in the heat-treating process.

  • Heat Treating
  • Inerting
– Oil & Gas

The oil and natural gas industry utilizes nitrogen to increase reservoir reserves and fracture hydrocarbon-bearing formations to significantly increase the production of oil and gas while improving operating efficiency.

  • Enhanced Oil Recovery
  • Well Hydraulic Fracturing
– Refining

Nitrogen gas used to blanket storage tanks and purge pipelines It can also strip Volatile Organic Compounds (VOCs) from chemical process streams and wastewater while reducing VOC emissions.

  • VOC Treatment & Recovery
– Diving
– Electronics
– Glass
– Laboratories
