Hydrochloric acid electrolysis
Thread Content
Which company in China uses hydrochloric acid electrolysis technology? We also need to electrolyze hydrochloric acid to recover chlorine gas – where can we find hydrochloric acid electrolysis equipment?
Currently, there are two methods for converting the by-product hydrogen chloride into chlorine: Sumitomo’s catalytic method and Wood’s electrolytic method. Advantages of Sumitomo: Low investment from an early stage, low energy consumption ； The disadvantages are: large area, high catalyst cost, and the equipment requires high resistance to high temperatures and acids ； Advantages of wood: small size, high equipment utilization rate, no need for special equipment ； The disadvantages are: high one-time cost and high energy consumption.
Overall, Wood’s electrolyzer is currently the more mature one. It mainly depends on the profitability and scale of your company. If several tens of thousands of tons of hydrochloric acid are produced as a by-product per year, then Wood’s electrolyzers could be considered; otherwise, find a way to have it processed externally.
Our company produces a considerable amount of hydrochloric acid as a by-product, mainly because we need to recover chlorine gas. Do you know which companies in China use Wood’s electrolyzers?
I’d like to know that too; if anyone knows, please share some information
We are currently in the process of construction; it involves 4 electrolyzers capable of producing 100,000 tons of chlorine, with a cost of 200 million
By-product hydrochloric acid? What’s in it? Can it be electrolyzed directly? Refining followed by electrolysis should be used; domestic technology can handle this, we can discuss it
A hydrochloric acid electrolyzer is an oxygen-cathode hydrochloric acid electrolyzer; pure hydrochloric acid is used at a concentration of 14.5% for electrolysis, otherwise it is necessary to filter out the impurities present. The ODC membrane and ion membrane in such electrolyzers are particularly sensitive to heavy metal ions, and there is no research on this topic in China.
Can this wood-based process produce pure hydrogen?

Does anyone have process information on the electrolytic production of hydrochloric acid using wood? Could you provide a copy for study*? 604721435@qq.com
