The development of my country’s chlor-alkali industry is improving. Greening and large-scale development have become the development trend.

The chlor-alkali industry refers to the industry that uses saturated salt water to produce chlorine, hydrogen, caustic soda, chlorine, hydrogen and other chemical products. As an important basic chemical industry, the products produced by chlor-alkali are not only used in the chemical industry, but also in medicine, glass, plastics, papermaking, chemical fiber and other industries. In recent years, with the continuous improvement of my country’s economy, the demand for chlor-alkali market has been continuously released, and the scale of the industry has gradually expanded.

According to the “2022-2026 Chlor-Alkali Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center, my country’s chlor-alkali industry Started in the 1920s, through continuous development and technological upgrading, my country has become the world’s largest producer of chlor-alkali products, with chlor-alkali production accounting for more than 50% of global production. Against the background of increasingly stringent environmental protection supervision and increasing production technology, the chlor-alkali industry has entered a stage of structural adjustment, and the industry is gradually developing in the direction of green, high efficiency, and scale.

Polyvinyl chloride and caustic soda are important downstream markets for the chlor-alkali industry. In 2021, my country’s polyvinyl chloride industry output will be about 22 million tons, a year-on-year increase of about 9.8%. The output is mainly concentrated in northwest, North China and other regions; the caustic soda industry output will be 3620 tons. Around 10,000 tons, a year-on-year increase of approximately 4.0%, with output mainly concentrated in North China, Northwest China and other regions. Benefiting from the increase in the production of polyvinyl chloride and caustic soda, the chlor-alkali market size has shown a steady upward trend, with the market size in 2021 being approximately 254.6 billion yuan.

From the perspective of the industrial chain, the upstream of the chlor-alkali industry chain is the raw material layer, involving raw salt, calcium carbide, coke and other raw materials, the midstream is the production layer of caustic soda, chlorine, polyvinyl chloride and other products, and the downstream is the application layer. From the perspective of production technology, chlor-alkali production processes include diaphragm electrolysis, ion exchange membrane method, etc. Among them, ion exchange membrane method is currently the mainstream production process of chlor-alkali products in my country.

From the perspective of market competition, there are a large number of enterprises in my country’s chlor-alkali industry. Among them, large enterprises include Shandong Haihua, Wanhua Chemical, Binhua Co., Ltd., Xinjiang Tianye, Zhongtai Chemical, Juhua Co., Ltd., Jiahua Energy and other enterprises. Among them, Zhongtai Chemical has a relatively high market share. The concentration of the chlor-alkali market is low, with the concentration of caustic soda CR5 being less than 12.5% ​​and the concentration of polyvinyl chloride CR5 being less than 23.0%. However, with the deepening of supply-side structural reform and lagging companies accelerating their exit from the market, the concentration of the chlor-alkali industry is gradually increasing.

Industry analysts said that after continuous development, my country has become a major producer of chlor-alkali products in the world. At the same time, the structure of the chlor-alkali industry has also been optimized and adjusted. The development of the industry is shifting towards scale, greenness and high efficiency. There are many companies in the chlor-alkali industry, and market competition is relatively fierce. Against the background of increasingly stringent environmental protection supervision, companies with large scale, low energy consumption, and high technical level have more competitive advantages.
