The function of LPG CNG Switch: switch of liquefied petroleum gas/compressed natural gas. Liquefied petroleum gas is a colorless volatile liquid obtained by liquefying natural gas or petroleum under pressure and cooling in an oil refinery. It is very easy to ignite spontaneously. When its content in the air reaches a certain concentration range, it can explode when it encounters an open flame.
LPG is used as a raw material for petrochemical industry, as a solvent for low-temperature extraction in subcritical biotechnology, and as a fuel. Liquefied petroleum gas is mainly used as a raw material for petrochemicals, used for hydrocarbon cracking to produce ethylene or steam reforming to produce synthesis gas, and can be used as industrial, civil, and internal combustion engine fuel. The main quality control indicators are evaporation residue and sulfur content, and sometimes olefin content is also controlled.
Compressed Natural Gas (CNG) refers to gaseous natural gas compressed to a pressure greater than or equal to 10 MPa and no greater than 25 MPa. The natural gas is pressurized and stored in a gaseous state in a container.
Compressed natural gas is an ideal alternative energy source for vehicles, and its application technology has become increasingly mature after decades of development. It has the characteristics of low cost, high efficiency, no pollution, safe and convenient use, etc., and it is increasingly showing strong development potential. Natural gas filling stations are generally divided into three basic types, namely fast filling type, ordinary (slow speed) filling and a mixed type of the two.
Compressed natural gas is also used in the city gas industry, especially as a fuel for residents. With the improvement of people's living standards and the enhancement of environmental protection awareness, the demand for natural gas in most cities has increased significantly. The economic benefits of natural gas (pipeline natural gas) as a civilian fuel are also greater than industrial fuels.
