Liquefied Natural Gas (LNG)

A clear, colorless, non-toxic liquid Gas

LNG is liquefied natural gas, a clear, colorless, non-toxic liquid .Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gaseshelium, water, and heavy hydrocarbons, which could cause difficulty downstream. 

The natural gas is then condensed into a liquid at close to atmospheric pressure by cooling it to approximately −162 °C (−260 °F);  This shrinks the volume of the gas 600 times, making it easier to store and ship to energy-hungry towns and cities overseas.
