natural gas, largely composed of methane, which has been refrigerated to a liquid. The boiling point of methane at atmospheric pressure is -161°C. Because of its low critical point, it must be cooled to below this temperature before it can be liquefied by pressure. Once liquefied, it can be stored in well-insulated vessels and can be conveniently transported. It is used as an engine fuel.

LNG is more practical than liquefied petroleum gas or other liquid gases, particularly for use in large volumes, because it has the same chemical composition as natural gas. This fact and the growing demand for natural gas have stimulated LNG production.
