Liquefied Natural Gas – LNG

LNG stands for Liquefied Natural Gas or Liquid Natural Gas, and as the name implies, it is traditional natural gas which has been cooled to the point of liquefaction. Liquefied natural gas is predominantly methane, CH4, with some mixture of ethane C2H6. It may contain traces of C3 and C4 hydrocarbon molecules. It is odorless, colorless, non-corrosive, and non-toxic.

LNG is converted to liquid form by a cooling process using cryogenic heat exchangers, for ease of storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state, making it also much more dense than gaseous natural gas. At the delivery terminals, LNG is vaporized and transported to customers as natural gas. LNG is used predominantly as fuel for power generation.
