Application and use In its liquid form nitrogen is used as a cryogen for many applications where very low temperatures or rapid temperature reduction is required. Some common applications where nitrogen is used are: Artificial Insemination Nitrogen is often used for the storage of semen samples for artificial insemination of cattle.

Blanketing and inerting Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. Food packaging Used in modified atmosphere packaging, liquid nitrogen can increase the shelf-life without the need for vacuum-packing, artificial preservatives or freezing Freeze-drying In the freeze-drying process, materials dissolved in water or organic solvents are frozen into particles or droplets.

A vacuum is applied to the freezing chamber along with a controlled amount of heat sufficient to drive off moisture by sublimation Glass Nitrogen and hydrogen are used in the float glass process for manufacturing flat glass.

In this process perfectly flat glass with a very high quality is achieved by floating liquid glass on a bath of molten tin Heat treatment Pure nitrogen is used to protect some of the most reactive metals during heat treatment. These metals readily form a protective oxide surface layer from the small amount of oxygen in the nitrogen and need no further protection Lasers Nitrogen is used as an assist gas for laser cutting of stainless steel, aluminium and non-metallic materials Metals Nitrogen is used in iron and steelworks applications for degassing and metal-stirring, purging, cooling, slag splashing, gas knives and as a carrier gas for injecting de-sulphurising compounds.

It is also used for aluminium-extrusion inerting Pipe-freezing Repairs can be made to a pipe containing a liquid by using liquid nitrogen to freeze a plug of liquid on each side of the section of pipe to be opened Purging Applications include inerting reactors and storage tanks, purging vessels and pipelines of flammable or toxic gases and vapours, and the sparging and pressure transfer of liquids Shrink-fitting Liquid nitrogen is used to shrink components so they are small enough to be inserted into another component Sample storage Liquid Nitrogen can be used to store medical or research samples such as blood, plasma and semen — safely.

Nitrogen is often used for the storage of semen samples for artificial insemination of cattle.

Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. The atmosphere and ambient temperature surrounding naturally respiring products such as fruit is actively controlled to provide optimum conditions for long-term storage.

Used in the inerting of printed circuit board reflow and wave ovens, to prevent oxidation and facilitate the use of weaker fluxes which decompose more easily without leaving a residue. Liquid nitrogen freezes food quickly, producing a higher-quality product compared to to conventional refrigeration. 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.

Heat Treating Parts Manufacturing. 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. 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.

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

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. 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.

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.
