Liquefied natural gas (LNG) is natural gas in a liquid form that is clear, colorless, odorless, non-corrosive and non-toxic. It is produced when natural gas is cooled to minus 259°F (-161.66°C) through a process known as liquefaction. 

During this process, natural gas, which is primarily methane, is cooled below its boiling point, and certain concentrations of hydrocarbons, water, carbon dioxide, oxygen and some sulfur compounds are either reduced or removed. LNG is less than half the weight of water. If spilled on water, it will float and then immediately vaporize if under atmospheric pressure.
