Nitrogen is found abundantly in the earth’s atmosphere and constitutes around 78% of the same. Because of extensive industrial applications, nitrogen is also known as the largest industrial gas. Nitrogen and liquid nitrogen are used in wide range applications including inerting, heat treating, reactor cooling, freezing, chilling, flour & dough cooling, meat mixing, modified atmosphere packaging, etc. Liquid nitrogen is generated in a cryogenic nitrogen plant by tapping air from the atmosphere which is compressed and cooled in heat exchangers to cryogenic temperatures. Then, compressed air is moved into a molecular sieve where impurities such as carbon dioxide, moisture and hydrocarbons are eliminated. Here, the air is moved into a high pressure distillation column where nitrogen is separated from others gases and is formed at the bottom of the distillation column. It is continuously distilled till it meets industrial and medical specifications.

High quality materials are used in the fabricating of cryogenic nitrogen plant. Manufacturing is done using the best available cryogenic technology. Materials used in the making should be able to withstand high temperature and pressure and must meet the standards of American Society of Mechanical Engineers (ASME). Nitrogen has wide range of applications for both gaseous and liquid form but it is primarily stored as a liquid because it is easy to transport and store. And, liquids are less likely to leak besides being economical. High quality standards must be complied in the manufacturing of the plant machinery.
