Nitrogen is colorless, odorless and tasteless. It is nonflammable,
will not support combustion and is not life-supporting.
The gas is slightly lighter than air and is only slightly
soluble in water. When liquid nitrogen is vaporized and
then heated it consumes a large amount of heat, making it
an ideal coolant.
Nitrogen is present in the atmosphere at a concentration
of 78.1%. Nitrogen is recovered from air in an Air Separation
Unit (ASU) where it is drawn off as a cryogenic liquid at
about -321°F. Nitrogen can then be distributed as a cryogenic
liquid or as a gas in cylinders. Nitrogen can also be generated
onsite, using various techniques.
Nitrogen has many commercial and technical applications.
Liquid nitrogen's cooling properties are used to freeze
food, blood and other materials; modify metal properties;
control reaction temperatures; cool concrete and simulate
cold operating conditions. Nitrogen gas is used to blanket,
purge or stir many chemicals or molten metals. The gas can
also be used to pressurize devices or pneumatically convey
materials, while keeping out contaminates like oxygen or
water.
Safety Informations
- Nitrogen is not toxic and non-reactive except at
high temperatures
- If insufficient oxygen is present, high nitrogen
concentrations cause asphyxiation and death. They are
no physiological warning signs to nitrogen enrichment
- Nitrogen does not support combustion
- Liquid nitrogen has the capacity to inflict dangerous
frost bites
