storage tank for lpg
Liquefied petroleum gas is one of petroleum products. The English name is liquefied petroleum gas, or LPG for short. It is a colorless, volatile gas obtained by pressurizing, cooling and liquefying refinery gas or natural gas (including oilfield associated gas). The liquefied petroleum gas obtained from refinery gas is mainly composed of propane (more than 95%), propylene, butane, and butene, and also contains a small amount of pentane, pentene, and trace sulfur compound impurities.
The composition of the liquefied gas obtained from natural gas is substantially free of olefins. Liquefied petroleum gas is mainly used as petrochemical raw material, 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. Its main quality control indicators are evaporation residue and sulfur content, etc., and sometimes olefin content is also controlled. Liquefied petroleum gas is a flammable substance. When the content in the air reaches a certain concentration range, it will explode when it encounters an open flame.
