About Liquid Nitrogen:
Liquid nitrogen is inert, colorless, odorless, noncorrosive, nonflammable, and extremely cold. Nitrogen makes up the major
portion of the atmosphere (78.03% by volume, 75.5% by weight). Nitrogen is inert and will not support combustion;
however, it is not life supporting.
Nitrogen is inert except when heated to very high temperatures, where it combines with some of the more active metals,
such as lithium and magnesium, to form nitrides. It will also combine with oxygen to form oxides of nitrogen and,
when combined with hydrogen in the presence of catalysts, will form ammonia.
Since nitrogen is noncorrosive, special materials of construction are not required to prevent corrosion. However, materials
of construction must be selected to withstand the low temperature of liquid nitrogen. Vessels and piping should
be designed to American Society of Mechanical Engineers (ASME) specifications or the Department of Transportation
(DOT) codes for the pressures and temperatures involved.
Although used more commonly in the gaseous state, nitrogen is commonly stored and transported as a liquid, affording
a more cost-effective way of providing product supply.
Liquid nitrogen is a cryogenic liquid. Cryogenic liquids are liquefied gases that have a normal boiling point below –130°F
(–90°C). Liquid nitrogen has a boiling point of –320°F (–196°C). The temperature difference between the product and
the surrounding environment, even in winter, is substantial. Keeping this surrounding heat from the product requires
special equipment to store and handle cryogenic liquids.
A typical system consists of the following components: a cryogenic storage tank, one or more vaporizers, and a pressure
and temperature control system. The cryogenic tank is constructed like, in principle, a vacuum bottle. It is designed
to keep heat away from the liquid that is contained in the inner vessel. Vaporizers convert the liquid nitrogen to its
gaseous state. A pressure control manifold controls the pressure at which the gas is fed to the process. Processes that
use nitrogen as a liquid do not require the vaporizers and pressure control manifold.
