Liquefied Natural Gas (LNG), the main component of which is methane, is recognized as the cleanest energy source on earth. Colorless, odorless, non-toxic and non-corrosive, its volume is about 1/625 of the same volume of gaseous natural gas, and the weight of liquefied natural gas is only about 45% of the same volume of water. Uses: The world's advanced environmental protection countries are promoting the use of LNG. In addition to being used as fuel for power plants, factories, and household users, the methane contained in it can be used to manufacture fertilizers, methanol solvents, and synthetic acetic acid and other chemical raw materials; The ethane and propane contained in it can be cracked to generate ethylene and propylene, which are important raw materials for plastic products. In addition, the ultra-low temperature LNG can provide a large amount of cold energy in the process of transforming into a normal temperature gas state under atmospheric pressure. Recycling can also be used for 6 low-temperature purposes: separation of air to produce liquid oxygen, liquid nitrogen, liquefied carbon dioxide, dry ice production, use of cold energy for power generation, production of frozen food or use in frozen warehouses, rubber, plastic, iron filings Low temperature crushing treatment of industrial waste, desalination of sea water.
