Production of chlorine dioxide from sodium chlorite
Thread Content
I’d like to learn more about this. Specifically, when it comes to the production of chlorine dioxide using sodium chlorite and sodium chlorate, the price of sodium chlorite is three times that of sodium chlorate. So why do so many companies still choose to use sodium chlorite for this purpose? I hope everyone can discuss this further
It is currently known that chlorine dioxide produced from sodium chlorite has a high mass concentration and good quality; however, the details are not entirely clear
Contact the manufacturers of chlorine dioxide generators by phone; the main methods for producing chlorine dioxide currently are electrolysis, sodium chlorate method, and sodium sulfite method. Specific details: The price of the complete set of equipment for chlorate and chlorine dioxide generation is slightly higher than that for sodium hypochlorite, while the cost of electrolytic-based equipment is relatively high. Currently, there are mainly two reasons why companies choose chlorine dioxide generators using the sodium chlorite method: 1. Requirements from design institutes ； 2. The reactor using sodium chlorite does not require heating compared to those that use sodium chlorate, which is more convenient for ordinary enterprises ； 3. With the sodium chlorite method, the reaction rate is >90%, whereas it is only around 80% using the sodium chlorate method (not a key point, I guess). However, the purchase price of sodium chlorite is relatively high, and the number of companies that inquire about chlorine dioxide generators and choose sodium chlorite is gradually decreasing.
