Nitrogen gas production plant is used for production of nitrogen for various industrial and medical applications. The gaseous element makes up around 78% of planet earth’s atmosphere by volume and is also found inside the earth. However, nitrogen for commercial purposes is generated via nitrogen plant because atmospheric air comprises of only 87% whereas industrial and medical applications need around nitrogen with purity up to 99.99%. Most of the industries now prefer to install onsite plants for generation their own gas. The earlier method of meeting your requirements by subscribing supplies from an industrial gas retailer is now out-dated as it is subject to uncertain supply. How Do We Make Liquid Nitrogen
Nitrogen plant taps atmospheric air which is compressed in the air separation unit before being sent into the molecular sieve where impurities such as carbon dioxide, hydrocarbons and moisture are removed. Then, the air is moved into exchangers where it is cooled to a cryogenic liquid. Afterwards, it is moved into a high pressure distillation column where nitrogen separated from other gas and is distilled till reaches desired purity specifications. Nitrogen is deposited at the top of distillation column.
Applications of nitrogen gas
Nitrogen is an important industrial gas in world, nitrogen production plant cost. In fact, it is the largest industrial gas in the manufacturing of of fertilizers, nitric acid, nylon, dyes and explosives. It is reported that annually over 150 million tonnes of ammonia is produced. Moreover, the gas is also used for providing inerting atmosphere which is used for preservation of food and making of diodes and transistors. The non-reactive gas is used annealing stainless steel products.
Various applications of nitrogen include:
- Applied in wind tunnels, heat treating furnaces and autoclaves to help create incredibly strong but lightweight materials
- Nitrogen is used with other welding gases to weld auto parts, frames, mufflers and other components
- It is very effective in propelling liquids through pipelines & is used to shield oxygen-sensitive materials from the air
- Perfect for prevention of oxidation and is an important component in the heat-treating process
- Gaseous nitrogen is used for purging, pressure transferring, mixing and blanketing. It provides protection from moisture intrusion, oxidation, degradation and contamination
- Used for freezing and transport of food products
- Cryopreservation of biological samples such as sperm, eggs, and animal genetic samples
- Coolant for superconductors, vacuum pumps, and other materials and equipment
- Cryotherapy to remove skin abnormalities
- Provides protection for materials from oxygen exposure
- Rapid freezing of water or pipes to allow work on them when valves aren’t available
- As a source of extremely dry nitrogen gas
- Used for branding cattle.
