Operation process of LPG injection kit

  • With the development of the petrochemical industry, LPG Injection Kit, as a basic chemical raw material and a new type of fuel, has attracted more and more attention. In terms of chemical production, liquefied petroleum gas is a by-product of crude oil catalytic cracking and thermal cracking in refineries. The main components of catalytic cracking gas are as follows (%): hydrogen 5-6, methane 10, ethane 3-5, ethylene 3, propane 16-20, propylene 6-11, butane 42-46, butene 5-6, 5-12 hydrocarbons containing more than 5 carbon atoms. It is used to produce synthetic plastics, synthetic rubbers, synthetic fibers and pharmaceuticals, explosives, dyes and other products.

    It is a colorless volatile liquid obtained from refinery gas or natural gas pressurized and cooled down, and it is flammable. When the content of liquefied petroleum gas in the air reaches a certain concentration range, it will explode when exposed to an open flame. The main components of liquefied petroleum gas obtained from refinery gas are propane, propylene, butane, butene (can be a mixture of one or several hydrocarbons), and contain a small amount of pentane, pentene and trace sulfide impurities.

    Among them, carbon oxysulfide is removed by alcohol amine absorption tower, and sulfide is removed by alkaline washing method. The liquefied gas obtained from natural gas (including oilfield associated gas) is basically free of olefins. The top product of the stable gasoline operation of the refinery is liquefied petroleum gas. It can be used as engine fuel, household fuel, basic organic synthesis raw material, etc.

    LPG Injection Kit is used as a raw material for petrochemical industry, 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.
