LNG (Liquefied Natural Gas) is a natural gas liquefied by cryogenic refrigeration at minus 162^oC after removal of impurities. LNG composition is primarily methane.

Application:

• LNG takes up just about 1/600^th the volume of natural gas in standard conditions (15^oC, 1atm)), allowing its large quantities to be transported from LNG production places to countries around the world across oceans using ocean tankers with a tonnage of 140,000 to 260,000 m³. At the receiving facilities, LNG is transferred back into its gaseous state and sent via pipeline for distribution to consumers.
•  
• Similarly to dry gas, LNG is used as a fuel/ feedstock for generating electricity, fertilizer production, methanol, DME, industrial customers and residential areas used.
•  
• LNG is transported by trucks, trains, coastal tankers with capacity of 2,500 m³ – 12,000 m³  from receiving terminals to remote areas, consumers located far from the pipeline, in the coastal areas and offshore islands.
•  
• Nowadays, LNG has been widely traded in international markets and became an important energy source for many countries as Japan, Korea, Taiwan, China, European and North America countries. A majority of the world’s LNG supply comes from the Middle East, Australia and Russia.
•  
• In developed countries, LNG is normally used as a fuel for ships, trains and heavy trucks to minimize environmental pollution.
