Aerospace & Aircraft

Essential to the aerospace & aircraft industry, nitrogen is used in high Reynolds number wind tunnels, heat treating furnaces and autoclaves to help create incredibly strong but lightweight materials. Nitrogen is also used as an assist gas for laser cutting applications.

Chemicals

Used as a pressurizing gas, nitrogen can help propel liquids through pipelines. It is also used to shield oxygen-sensitive materials from the air and to remove volatile organic chemicals from process streams.

Metal Production

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

Oil and 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, and to improve operating efficiency.

Automotive & Transportation

Assembly plants, tier 1s and tier 2s use nitrogen in combination with other welding gases to weld auto parts, frames, mufflers and other components because of its ability to provide the necessary atmosphere needed to produce adequate welds with any material. It’s also an important safety component in airbags.

Healthcare

Nitrogen NF is used as a cryogen to freeze and preserve blood, tissue, and other biological specimens, and to freeze and destroy diseased tissue in cryosurgery and dermatology. It is also used to power medical devices.

Energy

As an inert industrial gas, nitrogen 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.

Food & Beverage

Nitrogen is a key cryogenic agent in cooling, chilling and food freezing. Because of its extremely cold temperatures, immersion freezing in liquid nitrogen is the fastest freezing method known for producing Individually Quick Frozen (IQF) foods. Nitrogen also plays a key role in reducing spoilage, discoloration and off–flavors, giving strength to retail packaging.

Pharmaceuticals and Biotechnology

Gaseous nitrogen is commonly used for purging, pressure transferring, mixing and blanketing — protecting a process 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.

Refining

An industrial gas used to blanket storage tanks and purge pipelines, nitrogen can also strip Volatile Organic Compounds (VOCs) from chemical process streams and wastewater, and reduce VOC emissions.
