About Nitrogen
Nitrogen constitutes 78% of the air, has
a gaseous specific gravity 0.967, and
has a boiling point 0f -320.5oF
(-195.8oC) at atmospheric pressure. It
is colourless, odourless and tasteless.
Nitrogen is often used as an inert gas
due to its non-reactive nature with many
materials. However, nitrogen can form
certain compounds under the influence of
chemicals, catalysts, or high
temperature.
Commercial nitrogen is produced by
variety of air separation processes,
including cryogenic liquefaction and
distillation, adsorption separation, and
membrane separation. |

Uses of Nitrogen
- Gaseous Nitrogen is used in the
chemical and petroleum industries for
storage tank blanketing and vessel
inerting applications.
- it is used extensively by the
electronics and metals industries for
its inert properties.
- Liquid nitrogen, produced by the
cryogenic air separation process, finds
wide uses as refrigeration in
applications such as cryogenic grinding
of plastic and food freezing.
- For manufacturing of ammonia (NH3), a
very important chemicals for
manufacturing of fertilizer.
- It is used to fill hauler truck's
suspension in the mining industry
- Liquid Nitrogen is used for fixing
bushes plastic grinding e.t.c. |
