What is LNG LNG? How does an LNG vaporizer work? What does it do?

Liquefied natural gas.

is to compress natural gas.

Use ultra-low temperature (-162) to process into liquid, because natural gas can be converted into liquid at ultra-low temperature, so that the transportation volume is large, is more than 600 times that of compressed natural gas, and the gasifier will change the liquid state into gas, and the compressed natural gas refueling station can be refueled to the car, if it is an LNG refueling station, then there is no need for a vaporizer, you can directly refuel the car, and the LNG refueling station must go through less.

LNG is the English abbreviation of liquefied natural gas! Natural gas is methane, a fuel that is colorless, odorless and non-toxic. The working principle of an LNG vaporizer is simply that a liquid becomes a gas (that is, gasification) and needs to absorb heat.

The liquid natural gas (LNG) communicates with the atmosphere through the pipeline, pipeline or blade inside the vaporizer, and the liquid gas absorbs the heat in the air and vaporizes it (the boiling point of LNG is -162). Why gasification? Because natural gas in gaseous form is widely used in industry, chemical industry, life, power generation, automobile industry and so on!

Cars are also fueled by LNG! It works better, but LNG cars cost more to build! The role of the LNG gasifier is to gasify the liquid gas into gaseous natural gas!!

LNG stands for Liquefied Natural Gas. The main component of liquefied natural gas (LNG) is methane, which is recognized as the cleanest fossil energy source on the planet. It is colorless, odorless, non-toxic and non-corrosive, and its volume is about 1 625 of the same volume of gaseous natural gas, and the mass of liquefied natural gas is only about 45% of the same volume of water.

Extended information: Applications of LNG.

1. LNG cold energy utilization.

To facilitate the storage and transportation of natural gas, it is necessary to liquefy it at a low temperature of -162 and store it in a tank made of special materials. According to the law of conservation of energy, the huge amount of energy consumed during the compression liquefaction process is released again in the vaporized state of LNG. The energy produced in this process is called "cold energy".

2.The use of LNG vehicles.

Cars are powered by natural gas instead of gasoline**. Natural gas vehicles appeared in China as early as the 70s of the last century. After decades of development, good results have been achieved in both technology and popularization.

LNG is Liquefied Natural Gas.

Liquefied natural gas (LNG), the main component of which is methane, is considered to be the cleanest fossil energy source on the planet. It is colorless, tasteless, non-toxic and non-corrosive, and 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 same volume of water.

The manufacturing process is to first purify the natural gas produced in the gas field, and after a series of ultra-low temperature liquefaction, it is transported by LNG ship. LNG is a relatively advanced energy source because it causes very little air pollution and emits a lot of heat.

Apply. The world's advanced environmental protection countries are promoting the use of LNGIn 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 for the manufacture of fertilizers, methanol solvents and synthetic acetic acid. In addition, the ethane and propane contained in it can be cracked to form ethylene and propylene, which are important raw materials for plastic products.

In addition, in the process of transforming ultra-low temperature LNG into a gaseous state at room temperature under atmospheric pressure, it can provide a large amount of cold energy, which can also be used for 6 low-temperature purposes: air separation to produce liquid oxygen, liquid nitrogen, liquefied carbon dioxide, dry ice manufacturing, the use of cold energy for power generation, the manufacture of frozen food or used in frozen warehouses, low-temperature crushing treatment of industrial wastes such as rubber, plastics, iron filings, and seawater desalination.

LNG is the abbreviation of Liquefied Natural Gas in English, that is, liquefied natural gas. It is the product of the cooling liquefaction of natural gas (methane CH4) in a purified and ultra-low temperature state (-162, one atmosphere). The volume of liquefied natural gas is greatly reduced, about 1 600 of the volume of natural gas at one atmosphere, that is to say, 600 cubic meters of natural gas can be obtained after gasification of 1 cubic meter of LNG.

It is colorless and odorless, the main ingredient is methane, and there are few other impurities, which is a very clean energy source.

Basic parameters of LNG.

LNG uses.

Automotive: LNG is a clean and efficient energy source, as a high-quality vehicle fuel, compared with gasoline, it has the advantages of good anti-explosion performance, long engine life, low fuel cost, good environmental performance, high storage efficiency and good safety.

City gas: LNG can effectively ** areas where the pipeline network does not radiate, and can effectively alleviate the peak shaving demand in the case of peak city gas consumption. Seasonal changes and other factors lead to obvious uneven gas consumption, and the demand for peak shaving is prominent, and urban gas in various regions have built LNG peak shaving reserve facilities to alleviate the uneven gas consumption.

Industrial fuels and power generation: LNG transportation is flexible, and gasification devices can be installed when the pipeline is not radiated. LNG power generation has decisive advantages over traditional power plants in terms of environmental protection and peak shaving, and emerging distributed energy is the future development direction.

Cold energy utilization: Cold energy is the energy obtained by using a certain temperature difference under natural conditions. In the process of LNG gasification, about 870 kJ kg of low-temperature energy can be generated.

LNG cold energy can be used to generate electricity; Build a low-temperature cold storage next to the LNG receiving station to use LNG cold energy to freeze food; The use of LNG cold energy for low-temperature drying and crushing, applied to the pharmaceutical and food industries; The use of LNG cold energy to liquefy carbon dioxide, used in welding, fire fighting, frozen food, etc.; LNG cold energy can also be used to separate air to produce liquid nitrogen, liquid oxygen and liquid argon.

1. Gas is neither natural gas nor liquefied gas. Gas is a general term for gaseous fuels, which can be burned and release heat, and are used by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, coal-to-gas, etc.

If the bottled gas used at home is generally liquefied gas. Because the pressure of natural gas (LNG) is very high, it is very difficult to fill, and it is a large bottle of Pailing Xinzi (about twice as much as a liquefied gas bottle), so the bottled gas at home should be liquefied gas! Dust wheels.

2. Now, with the gradual expansion of the West-East Gas Transmission Project, pipeline gas is also used at home in the places where it passes, and the kind of pipe on the kitchen wall is ordinary natural gas.
