BOC - Liquid Nitrogen
Liquid nitrogen is produced in large quantities at air separation plants which liquefy and distil air into its constituent parts: nitrogen, oxygen and argon.
It is delivered to our customers by cryogenic tankers, into onsite storage, for use in high-volume customer applications.
It is stored as a cryogenic liquid in a vacuum-insulated vessel which can provide several days` supply and be used on demand as either a liquid or gas.
- Refrigerated liquefied gas
- Boiling point -196°C
- Gas/vapour heavier than air
- Odourless, colourless and non toxic
- Chemically inert at ambient temperatures
- Nitrogen 99.999%
- Oxygen <5vpm
- Moisture <2vpm
- Argon is included in the nitrogen
In its liquid form nitrogen is used as a cryogen for many applications where very low temperatures or rapid temperature reduction is required.
The inert property of gaseous nitrogen enables it to be used for applications where a substance needs to be protected from oxidation or combustion by atmospheric air, or from contamination by moisture.
