LNG transportation

Liquefied natural gas (LNG), the main component of which is methane, is recognized as the cleanest fossil energy on earth. Colorless, tasteless, non-toxic and non corrosive, its volume is about 1 / 625 of the volume of the same amount of gaseous natural gas, and the mass of liquefied natural gas is only about 45% of the water in the same body. The manufacturing process is to purify the natural gas produced in the gas field, and transport it by LNG ship after a series of ultra-low temperature liquefaction. The combustion of liquefied natural gas has very little air pollution and gives off a lot of heat, so liquefied natural gas is a relatively advanced energy. Liquefied natural gas (LNG) is the liquid of natural gas after it is compressed and cooled to its freezing point (- 161.5 ℃), which is usually stored in a low-temperature storage tank of - 161.5 ℃ and about 0.1MPa. Its main component is methane, which is transported by special ship or oil tank truck and re gasified when in use. Since the 1970s, the world's LNG production and trade volume have increased rapidly
