Liquefied Natural Gas
Liquefied Natural Gas (LNG) is natural gas that has been cooled to a liquid state at about -260°F for shipping and storage, reducing its volume to about 1/600th of its gaseous state. LNG is odorless, colorless, non-toxic, and non-corrosive, but it poses hazards such as flammability when vaporized. It is primarily used for transporting natural gas over long distances where pipelines are not feasible. Recently, LNG has gained importance in global energy supply chains, providing security and flexibility in energy resources.
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state at standard temperature and pressure.
LNG is odorless, colorless, non-toxic and non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The liquefaction process involves removal of certain components, such as dust, acid gases, helium, 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); maximum transport pressure is set at around 25 kPa (4 psi) (gauge pressure), which is about 1.25 times atmospheric pressure at sea level.

Gas alam cair (LNG) adalah gas alam (didominasi metana, CH4, dengan beberapa campuran etana, C2H6) yang telah didinginkan menjadi bentuk cair untuk kemudahan dan keselamatan penyimpanan atau transportasi tanpa tekanan. Volume LNG sekitar 1/600 dari volume gas alam dalam keadaan gas pada suhu dan tekanan standar.
Natural gas was considered during the 20th century to be economically unimportant wherever gas-producing oil or gas fields were distant from gas pipelines or located in offshore locations where pipelines were not viable. In the past, this usually meant that natural gas produced was typically flared, especially since unlike oil, no viable method for natural gas storage or transport existed other than compressed gas pipelines to end users of the same gas. This meant that natural gas markets were historically entirely local, and any production had to be consumed within the local or regional network.
