What is LNG?
Liquefied Natural Gas (LNG) is simply natural gas in liquid form. Produced natural gas can be cooled (liquefied) to about -161°C (-260°F) at normal pressure after pre-treatment to condense into liquid form called Liquefied Natural Gas (LNG). This makes the transportation of natural gas to long distant markets possible since LNG takes up about 1/600th the volume of its gaseous form.
LNG is usually transported in cryogenic vessels and kept in liquid form by auto-refrigeration, whereby any heat additions are balanced by the energy lost from LNG vapor vented out of storage and used to power the vessel. Once at its destination, the LNG is re-gasified and supplied to end users.
What is GTL?
Gas to liquids (GTL) is a chemical process in which natural gas is converted to gasoline or diesel fuel. The conversion - either via direct conversion or via syngas in the Fischer Tropsch process - results in synthetic super clean liquid fuels. The final product is easier to transport and targets wider markets of petroleum products.
