Liquid nitrogen, or simply liquid nitrogen, is actually the odorless and colorless nitrogen gas that is obtained by the fractional distillation of air. This product is considered one of the most widely used liquids. Liquid nitrogen is stored as a liquid gas at low temperatures.

Nitrogen is one of the inert gases that makes up 78% of the air around us. This element turns into a liquid at a temperature of minus 196 degrees Celsius. In recent years, with the advancement of sciences related to stem cells and other medical applications, the use of liquid nitrogen (LN2) has rapidly expanded.

However, unfortunately, the lack of awareness and familiarity with the use of this substance has led to a number of serious accidents and injuries. These accidents have occurred not only during use but also during transportation and storage.

The temperature of liquid nitrogen is at its boiling point of less than minus 320 degrees Fahrenheit (minus 196 degrees Celsius).

About 700 liters of nitrogen in gas form is converted to one liter of liquid nitrogen.

Applications of Liquid Nitrogen

Liquid nitrogen is one of the most widely used products. This product has various applications. Some of the applications of this product include:

Aerospace and aviation industry;

Beverage and food production industry;

Healthcare and medical industry;

Pharmaceutical industry;

Metal production industry;

Oil and gas industries;

Welding industry

Application of Liquid Nitrogen in Industry

This substance has numerous applications in the industrial sector. For example, considering the significant increase in volume of nitrogen when converting from liquid to gas, it can provide the necessary pressure for the transportation of refinery fluids. Additionally, nitrogen can be a good protector against the combination of materials with oxygen, thus it is used to prevent oxidation, a process known as Banketing or nitrogen gas covering.

Other applications include its use in the cooking industry, welding, aerospace, etc. Since one of the applications of this product is to assist in cooling and chilling food, it is used for preserving food items and meat products. Currently, liquid nitrogen is used for treating skin problems, skin cancer, etc.

This product is also used for manufacturing electronic components and as a protective material in industrial welding.
