       1. Petrochemical production mainly includes oil and gas processing and refining, organic chemical industry and polymer production.Petrochemical production refers to the production of chemicals using petroleum as raw materials in the chemical industry, including natural gas chemical industry in a broad sense.As a new industry, petrochemical industry was formed with the development of petroleum refining industry in 1920s.
       2. The scope of petrochemical industry: there are many kinds of chemicals produced by petroleum and natural gas with a wide range.Petrochemical raw materials mainly include various petroleum fractions and refinery gas, oilfield gas and natural gas produced in the process of petroleum refining.Olefins such as ethylene, propylene and butadiene and aromatic hydrocarbons such as benzene, toluene and xylene can be obtained from petroleum fractions (mainly light oil) through hydrocarbon cracking and pyrolysis gas separation. Aromatic hydrocarbons can also come from catalytic reforming of light petroleum fractions.Synthetic gas can be produced from light petroleum distillate and natural gas by steam conversion and heavy oil by partial oxidation to produce synthetic ammonia and methanol.
       3. The petrochemical industry is the pillar industry of our country.Petrochemical industry production line is long, involving a wide range of crude oil, refined oil, natural gas and other oil and gas pipeline nearly 6000km, gas station 2.40,000, petrochemical enterprises of oil fields, oil refineries, refineries, chemical plants, oil depot, gas stations, oil (gas) pipelines throughout the country cities, towns, stations, docks, hotels, thousands of households.
The petrochemical industry has become inseparable from modern production process of vacuum technology. KIMMET vacuum pump oil helps the vacuum system in the production process more stable, cleaner, more economical and more environmentally friendly.
