Liquefied Natural Gas (LNG for short), the main component is methane, is recognized as the cleanest energy on earth. Can LNG trucks be directly filled? Next, I will give you a specific analysis and introduction.
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. Its manufacturing process is to first purify the natural gas produced in the gas field, and then transport it by LNG ships after a series of ultra-low temperature liquefaction. The combustion of liquefied natural gas has very little air pollution and emits a large amount of heat, so liquefied natural gas is a relatively advanced energy source.
Liquefied natural gas is used in the form of transportation. It is transported by many types of tankers. Before delivery, natural gas cannot be directly filled in the car.
Environmentally advanced countries in the world 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 as chemical raw materials such as fertilizers, methanol solvents, and synthetic acetic acid; in addition, the ethane and propane it contains can be cracked to generate ethylene and Propylene is an important raw material 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. The cold energy can be recovered and used in 6 low temperature applications: separation of air to produce liquid oxygen and liquid nitrogen , liquefied carbon dioxide, dry ice production, use of cold energy for power generation, production of frozen food or used in frozen warehouses, low temperature crushing treatment of industrial waste such as rubber, plastic, iron filings, seawater desalination.
