The future development trend of chlor-alkali industry

Chlor-alkali industry, also known as chlor-alkali industry, in the industry by electrolytic saturated sodium chloride solution method to produce sodium hydroxide ( NaOH ), chlorine ( Cl2 ) and hydrogen ( H2 ), and use them as raw materials to produce a series of chemical products, known as chlor-alkali industry. Chlor-alkali industry is one of the most basic chemical industries. In addition to the chemical industry itself, its products are also widely used in light industry, textile industry, metallurgical industry, petrochemical industry and public utilities. The core product of chlor-alkali industry is caustic soda. There are three main processes : diaphragm electrolysis, ion membrane electrolysis and causticization.

In recent years, with the continuous development of China 's economy, chlor-alkali market demand continues to release, the industry gradually expanded. At present, China has become the world ' s largest producer of chlor-alkali products, chlor-alkali production accounted for more than 50 % of global output. Chlor-alkali industry as an important part of the national economy, not only in China 's chemical materials industry is of great significance in the global economic development also has a pivotal role.

Chlor-alkali industry belongs to high energy consumption and high pollution industry. In the future, the development trend of chlor-alkali industry will change with the general direction of policy. Energy saving and emission reduction policy will drive the upgrading of production equipment of chlor-alkali enterprises. According to the energy conservation and emission reduction plan issued by the state council, in order to alleviate the constraints of resources and environment, cope with global climate change, promote the transformation of economic development mode, build a resource-saving and environment-friendly society, and enhance the ability of sustainable development, domestic requirements for energy conservation and consumption reduction are becoming increasingly strict. At present, the chlor-alkali industry is facing a new situation. The equal or reduced replacement of advanced process upgrading projects that meet the policy requirements is gradually being carried out. Competitive enterprises can further develop, uncompetitive enterprises can withdraw in an orderly manner, and industrial concentration and core competitiveness are constantly improving. Industry development to scale, green, high efficiency direction.
