Liquefied Natural Gas (LNG)
LNG (Liquefied Natural Gas) is a natural gas liquefied by cryogenic refrigeration at minus 162oC after removal of impurities. LNG composition is primarily methane.
LNG takes up just about 1/600th the volume of natural gas in standard conditions (15oC, 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.
