It is recommended that students in the chlor-alkali field disclose the production scale of their respective chlor-alkali plants, as well as the manufacturers of electrolyzers and the main processes used

Is there anyone who can help us?
Our company’s production capacity is as follows: 100,000 tons of caustic soda, 100,000 tons of PVC, 20,000 tons of liquid chlorine, and 18,000 tons of high-purity hydrochloric acid. The production processes are as follows: In the caustic soda production unit, brine is processed into primary brine, then secondary brine; followed by electrolysis, and subsequent treatment to produce liquid chlorine, high-purity hydrochloric acid, and PVC. In the hydrogen chloride synthesis unit, calcium carbide is crushed to produce acetylene, which is then used for hydrogen chloride synthesis; from there, VCM is synthesized. Further processing includes conversion, pressure distillation, polymerization, drying, and packaging
Our company’s production capacity is as follows: 620,000 tons of caustic soda, 800,000 tons of PVC, 180,000 tons of propylene oxide, 500,000 tons of oxychlorination products, 100,000 tons of hydrogen peroxide, 100,000 tons of polyethers, and 40,000 tons of POP. There’s no need to explain the main process flow; the processes in the chlor-alkali industry are more or less similar. Electrolyzer: The ion-exchange membrane electrolyzer is from Asahi Kasei
Our company’s production capacity is as follows: 300,000 tons of caustic soda, 400,000 tons of PVC, 20,000 tons of liquid chlorine, and 45,000 tons of high-purity hydrochloric acid. The production processes are as follows: In the caustic soda production unit, salt is produced under vacuum – followed by primary brine, secondary brine, electrolysis, and further processing to produce liquid chlorine, high-purity hydrochloric acid, and PVC. In the hydrogen chloride production unit, hydrogen chloride is synthesized through evaporation. In the PVC production unit, calcium carbide is crushed to produce acetylene, which is then purified before VCM is synthesized. Subsequent steps include conversion, pressure distillation, polymerization, drying, and packaging
