What is LNG

WHat is LNG ?

Liquefied natural gas (LNG) is natural gas that has been cooled to the point that it condenses to a liquid,which occurs at a temperature of approximately -256°F (-161°C) and at atmospheric pressure. Liquefaction reduces the volume by approximately 600 times, making it more economical to transport between continents in specially designed ocean vessels. LNG technology
makes natural gas available throughout the world.To make LNG available for use, energy companies must invest in a number of different operations that are highly linked and dependent upon one another.

The major stages of the LNG value chain, excluding pipeline
operations between the stages, consist of the following.
• Exploration to fi nd natural gas in the earth’s crust and
production of the gas for delivery to gas users. Most
of the time natural gas is discovered during the search
for oil.
• Liquefaction to convert natural gas into a liquid state
so that it can be transported in ships.
• Shipping the LNG in special purpose vessels.
• Storage and Regasifi cation, to convert the LNG
stored in specially made storage tanks, from the
liquefi ed phase to the gaseous phase, ready to be
moved to the fi nal destination through the natural gas
pipeline system
