LNG Process

LNG Process

The LNG process involves several steps to bring natural gas from its source to its end user.

1. Gas Fields

Natural gas is produced in subsurface gas reservoirs and reached through drilling.

2. Gas Treatment and Liquefaction

The natural gas is sent by pipeline from the gas field to a processing plant, where impurities are removed from the gas. The gas is then cooled to negative 260 degrees Fahrenheit, transforming it into a liquid that is stored at subzero temperatures in specially-insulated storage tanks.

3. Shipping LNG

LNG is pumped into double-hulled ships specifically designed to handle the low temperature of LNG and transported by sea. These carriers are insulated to limit the amount of LNG that evaporates. 

4. LNG Regasification

Once an LNG ship is at the berth, it transfers its cargo to insulated onshore tanks for storage. When natural gas is needed, the LNG is transported within the terminal to a processing unit, where it is warmed to a temperature at which it reverts to its gaseous state. It can then be delivered by pipeline to homes, businesses and power plants.
