The Basics of Liquefied Natural Gas LNG

Liquefied Natural
Gas, or LNG, is natural gas in
its liquid form. When natural gas is cooled down to minus 259 degrees
Fahrenheit (or -161 degrees Celsius), it becomes a clear, colorless,
odorless liquid. Natural gas in liquid form, is only one six-hundredth
of the volume of its gaseous form, which makes it easier to be stored
and transport.
The natural gas is primarily Methane, with low
concentrations of other Hydrocarbons,
water, Carbon dioxide, nitrogen, oxygen and
some sulfur compounds. During the process known as liquefaction,
the natural gas is cooled down below its boiling point, and in the
process removing most of these additional compounds. The remaining gas
is primarily methane with only low amounts of other hydrocarbons.
Liquefied
natural gas weighs less than half the weight of water so it will float
if spilled on water.
