LNG is natural gas that has been processed to remove impurities and heavy hydrocarbons and then condensed into a liquid at atmospheric pressure by cooling it to approximately -160 degrees Celsius. LNG is about 1/600th the volume of natural gas making it much more cost-efficient to transport over long distances where pipelines do not exist or where moving natural gas by pipelines is not possible or economical, it can be transported by LNG vessels. LNG weighs less than one-half that of water.
LNG is Odourless, colorless, non-corrosive, and non-toxic. Natural gas is composed primarily of methane (typically, at least 90%), but may also contain ethane, propane and heavier hydrocarbons. LNG is stored in liquid state in tanks that have double-wall construction with extremely efficient insulation between the walls. LNG is converted to gas by vaporizing in LNG vaporizer and sent out for use as power generation fuel or other uses.
