Liquefied natural gas (LNG) is the same natural gas that liquefies it in a particular process for ease of transport. For the first time in the 19th century, English scientist Michael Faraday made a variety of natural gas and natural gas. LNG is flammable and when in contact, causes freezing.  

Name of matter (Persian language): Liquid natural gas 

The name of the substance (English): Liquefied Natural Gas 

  Brand (Farsi): LNG 

Branding (English): LNG 

Other names: Natural gas, Liquid natural gas, Cryogenic liquid 

Liquefied natural gas (LNG) consists mainly of methane, which is converted to the liquid for ease of transport. Natural gas has about 1,600 volumes of natural gas. LNG is colorless, odorless, not toxic and not corrosive. The process of liquefaction includes the removal of some heavy hydrocarbons, soot and acid gases from natural gas. Then the natural gas is compressed to liquid at 162 C at close pressure. LNG contains more than 95% methane and a low percentage of ethane and propane and other heavier hydrocarbons. The first experience of gas liquefaction dates back to the 19th century when English scientist Michael Faraday made various types of gas and natural gas liquid. The first LNG unit was built in 1912 in West Virginia, and the first commercial unit was launched in 1941 in Cleveland, Ohio. The first 5,000-metric LNG cargo shipped from Louisiana to Canvey Island in 1959 in England. In 1964, the first LNG export facility in Algeria was launched and the first LNG terminal in England was launched. Between 1972 and 1990, LNG trade was developed and its production began in Brunei, Indonesia, Abu Dhabi, Malaysia, Australia. Korea, Taiwan, and the United States also joined the importers of this product. Between 1994 and 2000, Qatar, Trinidad, and Nigeria came to the stage of development and production of this product has been achieved. In general, there are currently 17 LNG or Liquefaction units in 12 countries and 42 receiving or regasification terminals in 11 countries.  


LNG is used for fuel and energy purposes.
