What are the differences between green petrochemical industry and traditional chemical industry?

Petrochemical industry is a processing industry that produces petroleum products and petrochemical products with petroleum and natural gas as raw materials. The purpose is to make full use of various petroleum fractions, refinery gas, oilfield gas and natural gas produced in the process of petroleum refining. The outstanding feature of petrochemical industry is that there are many kinds and wide ranges of chemicals.

Coal chemical industry is a processing industry that uses coal as raw material to produce various chemicals, with the purpose of realizing the comprehensive utilization of coal energy. The outstanding feature of coal chemical industry is that coal is converted into gas, liquid and solid products by chemical methods, and then further processed.

In the traditional coal chemical industry, coke is produced by dry distillation of coal, and coke oven gas and coal tar are by-products, which mainly cooperate with the iron and steel industry. The general synthetic ammonia process is also classified into the traditional coal chemical industry. Modern coal chemical industry transforms coal into synthetic gas and fine chemical products by advanced means such as liquefaction, gasification and hydrogenation, and its development direction mainly includes: 1. Coal to olefins; Second, coal to natural gas; Third, changing coal into oil; 4. Making ethylene glycol from coal; Five, coal fine chemical industry.
