While China’s chlor-alkali industry is moving toward larger scales and more advanced technologies, it still lags behind international standards. The current problems are mainly reflected in the following three aspects. 1. The expansion speed is too fast. In 2004, thanks to the favorable market conditions for downstream products and the supply shortfall resulting from caustic soda manufacturers facing shortages of salt and electricity as well as production restrictions, the domestic caustic soda market experienced a booming situation that was rare in recent years. However, with the commissioning of a large number of new and expanded production facilities, the development pace of downstream products derived from caustic soda has failed to keep up with the pace of its expansion. In 2005, an additional 3.34 million tons per year of production capacity was added; such a large increase in facilities overburdened the already oversupplied domestic caustic soda market, resulting in a downturn in both the domestic caustic soda and polyvinyl chloride markets by mid-2005 – an inevitable consequence of too rapid expansion. 2. Planning is arbitrary. Some enterprises, particularly those with newly built chlor-alkali plants, lack a comprehensive and long-term analysis of the upstream and downstream product markets as well as the competitive landscape. It is believed that with electricity and salt, chlor-alkali plants can be built, and by leveraging the advantages of combined heat, electricity, and alkali production, a competitive edge can be gained in the market. The sales of liquid caustic soda were previously constrained by market radius limitations, and combined with measures to control overloading in transportation, this has made the regional nature of the liquid caustic soda market even more pronounced; therefore, it is essential to conduct thorough research on the surrounding markets before building chlor-alkali production facilities. Compared to previous years, domestic caustic soda exports from January to June 2005 amounted to 366,500 tons, exceeding the annual export volume for 2004. The increase in the export volume of caustic soda has alleviated pressure on the domestic caustic soda market, but given the global trends in the chlor-alkali industry, the surplus of caustic soda is intensifying market competition. Therefore, one cannot rely on an increase in exports to solve the problem of excess caustic soda in the domestic market. 3. The distribution is uneven, with a high concentration of enterprises in certain areas. At present, except for **, all provinces, municipalities, and autonomous regions across the country have caustic soda production facilities. However, due to China’s vast territory and varying economic levels across different regions, there are significant differences in the chlor-alkali market, leading to uneven development of this industry in various areas. Shandong Province is rich in salt resources and has an ample supply of electricity, giving it significant advantages in terms of raw materials for the production of chlor-alkali products. At present, its production capacity and output are far ahead of those in other parts of the country. Jiangsu Province also boasts abundant salt resources, and its chlor-alkali downstream products have been developed into a series; the pace of development in this sector is accelerating, with its production capacity now ranking second in the country. Furthermore, in some areas there is a high concentration of chlor-alkali manufacturers with scattered facilities; for example, there are 12 chlor-alkali enterprises in Shandong Province ； There are 2 in Leshan City, Sichuan Province ； There are 3 in Shizuishan City, Ningxia. The chlor-alkali products produced in the aforementioned regions cannot be consumed locally; they must be transported to nearby or more distant areas for sale. The larger the production volume, the wider the sales area required, which inevitably increases the selling costs and affects the economic profitability of the enterprises. Experts from the Ningxia Committee of the Revolutionary Committee of the Chinese Kuomintang, through investigation and analysis, believe that the chlor-alkali industry can be adjusted in the following three ways to ensure its orderly development. 1. The * and related functional departments should not merely play a guiding role for enterprises; they must also take into account the industrial chain and environmental impacts. *It is necessary to strengthen constraints on enterprises, and forcibly restrict the establishment of chlor-alkali plants with unreasonable layouts, in order to avoid waste of resources and human labor as well as vicious competition among enterprises. 2. As an infrastructure industry that requires substantial capital investment and has limited production capacity, the chlor-alkali industry must pursue a path of large-scale facilities, product diversification, and high quality. Expanding production scale is the correct direction for development, but attention must also be paid to the development of the entire industrial chain. Producing caustic soda and polyvinyl chloride should not be the only option for chlor-alkali manufacturers. Recently, the domestic PVC market has shown signs of weakness. Companies should abandon the traditional, monotonous production model based on chlor-alkali processes for PVC, and instead choose more suitable downstream products that suit the specific conditions of their region and company. These could be high-value fine chemical products such as bleaching powder and chloro-isocyanuric acid, which have good market prospects, thereby enhancing the companies’ competitiveness and resilience to risks. 3. Chlor-alkali enterprises should strengthen cooperation with research institutions to address as soon as possible the issue of \"advanced use coupled with lagging R&D\" in the current chlor-alkali industry. By fully considering market, raw material, and technical conditions, they should develop derivatives of alkali, chlorine, and hydrogen in a rational manner, move forward toward downstream applications, strive for the standardization of equipment, serialization of production, and diversification of operations. They should also cultivate a robust portfolio of fine chemical products, pursue a circular economy approach, and aim to establish an industrial chain of \"resources – products – recycled resources\" for ethylene, chlor-alkali, vinyl chloride, polyvinyl chloride, TDI/MDI, and polycarbonates, similar to that in the Shanghai Chemical Industry Park. ， ， -
There are three major issues in the development of the chlor-alkali industry, and at the core of these are the problems of high energy consumption and high pollution!
Another point is the localization of ion exchange membranes; only when we can use domestically produced ion exchange membranes can the chlor-alkali industry truly feel at ease!
Calcium carbide prices have risen, PVC prices have fallen; life is tough.
Especially after the financial crisis, the situation isn’t very optimistic! The chemical industry needs more technological updates and innovation!
The analysis is good. Hope that all levels will **provide guidance ； Chlor-alkali companies think carefully and make prudent decisions.
I would like to ask everyone: does anyone know which departments need to give approval for domestic ion exchange membranes? Thank you!
That’s not clear. Profits are getting smaller and smaller now. Real big actions are needed. .
The analysis is good; I think more effort should be put into developing the industrial chain
At present, production is saturated, but there are many projects to produce chlor-alkali, and their scale is too small. It is impossible to achieve economies of scale, and this is the biggest obstacle to the development of the chlor-alkali industry in China. In terms of the development of ion exchange membranes, it is impossible to make progress without the involvement of large chlor-alkali manufacturers; despite years of efforts, ion exchange membranes have still not been put into use, which is truly regrettable. **Small chlor-alkali manufacturers should be integrated to form large-scale chlor-alkali enterprises, so as to gain an advantage in the development of ion exchange membranes and new electrolyzer technologies, and thus avoid being controlled by others.
In my opinion, the caustic soda industry is one of the fundamental industries. The current aggressive and indiscriminate development of ion-exchange membrane caustic soda means that, from a strategic and long-term perspective, the coexistence of diaphragm caustic soda and ion-exchange membrane caustic soda, as well as the ratio between them, is of great importance. I hope that all our fellow countrymen will be mindful of potential dangers even as they pursue development! All ion exchange membranes are imported; the development of domestically produced ion exchange membranes is progressing slowly. I’m very worried that only a few manufacturers of diaphragm caustic will be able to survive after this economic crisis! On one hand, there is a reduction in production and closures of diaphragm caustic soda manufacturers, while on the other hand, there is significant expansion in the production of ion-exchange membrane caustic soda. It’s hard to understand, isn’t it? !
