What is LNG?

LNG stands for liquefied natural gas. As we wrote in our article on natural gas, gas is mainly transported through international pipelines. It is the international trade in natural gas and the pipeline network that brought LNG to life.

What is liquefied natural gas (LNG)?

What is LNG? Liquefied natural gas (also known as LNG) is natural gas cooled to a liquid state for the purpose of easier storage and transportation. When natural gas reaches about -260° Fahrenheit, through a liquefaction process using cryogenic heat exchangers, it becomes 600 times smaller than natural gas.

What is a LNG storage tank?

LNG is natural gas that has been cooled to -162 °C (-260 °F) to liquefy it for easier storage and transport. The LNG storage tank is primarily designed to keep the contents at this cryogenic temperature, preventing the gas from returning to its gaseous state. There are different types of LNG storage tanks which are based on design and intended use.

How is LNG stored?

The LNG is stored in cryogenic tanks and regasified before being used as fuel. The power plants take natural gas from natural gas pipelines, liquefy it in small-scale liquefaction facilities, and store it in cryogenic tanks. The LNG is regasified and burned by the power plants when needed.

How does LNG differ from natural gas?

LNG (liquefied natural gas) and natural gas have the same composition, but LNG is transported and stored as a liquid at very low temperatures. Other than that, everything else is the same as in the case of natural gas transported by pipeline in a gaseous state. LNG is colourless and odourless, non-toxic, but extremely flammable, and is odorized using tetrahydrothiophene or ethyl mercaptan.

What is the composition of LNG?

The composition of liquefied natural gas is almost identical to that of natural gas delivered by pipeline in the gaseous state. One cubic meter of liquefied LNG – after re-gasification – produces about 600 cubic meters of natural gas in normal condition.
