How does a liquid nitrogen plant work?
Liquid nitrogen is a colorless, odorless, non-flammable, non-corrosive and extremely cold element that finds a lot of applications including research and development.
Liquid Nitrogen Liquefaction :
Liquid Nitrogen Plant (LNP) draws out Nitrogen gas from the atmospheric air and then liquefies it with the help of Cryo cooler.
There are two methods through which Nitrogen can be liquefied:
1.Pressure Swing Adsorption with Cryo generator.
2.Distillation of liquid air.
Working principle of Liquid Nitrogen Plant
In a Liquid Nitrogen plant, the atmospheric air is first compressed to 7 bar pressure into compressor. This high temperature compressed air is then cooled in the external refrigeration system. Then, the cooled compressed air is passed through moisture separator to trap the moisture from the air. This dry compressed air is then passed through a bed of carbon molecular sieves where Nitrogen and Oxygen are separated from the air. Separated Nitrogen is then allowed to get through Cryo cooler which cools the gaseous Nitrogen to a liquid state at the boiling point of Nitrogen (77.2 Kelvin). Finally, the Liquid Nitrogen gets collected in Dewar`s vessel where it gets stored for several industrial purposes.
Uses of Liquid Nitrogen
Liquid Nitrogen is used in many applications because of its very low temperature and low reactivity. Some of the common applications are:
- It is used in cryo therapy to remove skin abnormalities
- Serves as a source of an extremely dry gas
- Freezing and transporting of food products
- Cooling of superconductors like vacuum pumps, and other equipment
- Cryo preservation of blood
- Cryo preservation of biological samples like eggs, sperms, and animal genetic samples.
- Preserving of animal`s semen
- Branding of cattle
- Cryosurgery (removing dead cells from the brain)
- Quick freezing of water or pipes to let workers work on them when valves are not available.
- Protects materials from oxidization.
- The shielding of materials from oxygen exposure.
- Other applications that include creating Nitrogen fog, making ice-cream, flash-freezing, flowering that shatters when tapped onto a hard surface.
If you require Liquid Nitrogen plant for your application, our team can guide you the best generators that can be operated and maintained without vast technical knowledge or training. We have easy to follow manuals and on-site training that enable our customer to properly check and maintain the whole system. Our systems require zero to very less maintenance.
