Liquefied Natural Gas

Natural gas is mostly methane (CH4) but also contains other hydrocarbons, water, nitrogen, sulfur, oxygen and carbon dioxide in varying amounts

Natural gas is converted to liquid in a refrigeration process called ‘liquefaction’ that removes most compounds except CH4.

The liquefaction process reduces natural gas by 1:610.

The purpose of converting natural gas to LNG is to make transportation over long distances economical.

LNG is transported on purpose built, double hulled ships in insulated tanks.

LNG is natural gas stored and transported as a liquid at atmospheric pressure at a temperature of -162 degrees C (-260 degrees F).

LNG is transported in a liquid state without refrigeration through the ‘boil off’ process which is the evaporation of a small amount of LNG which keeps the tanks cool, pressure constant and LNG at it’s boiling point.

When LNG is transported to it’s destination it is returned to gaseous state through a process called ‘regasification’ which is basically warming the LNG.

Natural gas is consumed by the industrial, power generation, residential, commercial and vehicle sectors.
