Chemical industry

Brief introduction of contents:

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 the development of the chemical industry has a direct impact on all sectors of the social economy, and the annual output value of the world's chemical products has exceeded $1.5 trillion. 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.

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.
