NITROGEN

NITROGEN

Nitrogen (N2) is colourless, odourless, tasteless, non-toxic and chemically inert gas.

Nitrogen accounts for 78% of air volume and can change its aggregate state. Liquid nitrogen is mobile, its boiling point is -195.8 oC and freezing point is -209 oC. In many fields of industry, nitrogen is useful for its ability to create a safe and sterile environment. Due to this reason, it is widely used in medicine, pharmacy, cosmetology and food industry.

Nitrogen is obtained from the atmospheric air by dividing it into composite parts.

The clients buying a considerable amount of nitrogen are supplied with special storage tank for the product and liquid nitrogen is delivered with semitrailers.

Fields of industry

 Medicine

Nitrogen is used for storing vital tissues, blood and its components, bodily liquids and cells at very low temperatures as well as for treatment of dermatological diseases (for example, removal of warts).

Since nitrogen is not characterised by oxidation, it is used for sterile storage of tools as well as a substance that pushes out oxygen in medication bottles. Nitrogen is used in producing various types of medication.

Food industry

Nitrogen is used for cooling, freezing and storing food products. Nitrogen is used as protective gas helping to push out oxygen from modified atmosphere packaging (MAP) and in the production of protective packaging gas mixtures.

Chemical industry

Nitrogen is used in the production of ammonia and production of carbamide – a powdery fertiliser with high content of nitrogen – from ammonia.

Transport and aviation

Liquid nitrogen is used for cooling the parts before their assembly and is also excellent in military aviation fuel systems (to reduce the risk of inflammation).

Safety

 Liquid nitrogen can cause cryogenic frostbites. More information on safe handling of nitrogen is provided in the material safety data sheet.
