What is Liquid Gas?
(Sometimes referred to as liquid gas) is a gas that has been turned into a liquid by cooling or compressing it. Examples of liquified gases include liquid air, liquefied natural gas, and liquefied petroleum gas.
Liquefied Natural Gas is natural gas that has been liquefied for the purpose of storage or transport. Since transportation of natural gas requires a large network of pipeline that crosses through various terrains and oceans, a huge investment and long term planning are required. Before transport, natural gas is liquefied by pressurization. The liquefied gas is then transported through tankers with special airtight compartments. When the tanks are opened and the liquid exposed to atmospheric pressure, the liquid boils off from the latent heat of the air or its container.
