Chemical industry

Chemical industry is a general term for enterprises and units engaged in the production and development of chemical industry. The chemical industry includes chemical industry, oil refining, metallurgy, energy, light industry, petrochemical industry, environment, medicine, environmental protection and military departments engaged in engineering design, fine and daily chemical industry, energy and power, technology development, production technology management and scientific research industries.

summarize

The chemical industry occupies an important position in the national economy of various countries and is the basic industry and pillar industry of many countries. The speed and scale of development of the chemical industry has a direct impact on all sectors of the social economy. At present, the annual output value of the world's chemical products has exceeded 1.5 trillion US dollars. Because the chemical industry has many categories, complex processes and diverse products, the pollutants discharged in the production are many kinds, large quantities and high toxicity, so the chemical industry is a major polluter. At the same time, chemical products in the processing, storage, use and waste disposal and other links may produce a large number of toxic substances and affect the ecological environment, endanger human health. The sustainable development of chemical industry is of great practical significance to the development of human economy and society.

Chemical industry classification

We divide the chemical industry into three categories: petrochemical, basic chemical and chemical fiber.

The basic chemical industry is divided into nine sub-categories: fertilizers, organic products, inorganic products, chlor-alkali, fine and special chemicals, pesticides, daily chemicals, plastic products and rubber products.

Chemical industry raw material classification

Inorganic chemical raw material

Elemental, industrial gas, inorganic base, inorganic acid, inorganic salt, oxide, non-metallic mineral, other unclassified inorganic chemical raw materials

Chemical ore

Sulfur ore, potassium ore, phosphate ore, boron ore, other chemical ore
