Extended data:

Industries that use petroleum as raw material to produce chemical products also include natural gas chemical industry. Petrochemical industry is a new industry formed with the development of petroleum refining industry since 1920s.

After World War II, a large number of chemical raw materials and products were transferred from coal and its by-products to oil and natural gas. Petrochemical industry has become the basic industry of chemical industry and occupies an extremely important position in the national economy. The raw materials of petrochemical industry are mainly various petroleum fractions and refinery gas produced during petroleum refining, as well as oilfield gas and natural gas.

After the 1970s, the petrochemical industry established a complete set of technical systems, and the products were applied to national defense, national economy and people's lives. The output of major products such as ethylene, plastics, synthetic fibers and synthetic rubber is often used to measure the development level of the world petrochemical industry. Petrochemical industry has become an important basic industry in developed countries because it can create high economic benefits.
