Our factory requires 80 to 150 grams per liter
Why use sodium carbonate? Isn't it better to use sodium hydroxide?
The poster mentioned that it absorbs the exhaust fumes! Chlorine? Is it exhaust gas treatment? 13% to 21% have it! :handshake
It was originally liquid caustic soda, but later the owner said it should be changed to sodium carbonate.~
I have never used sodium carbonate and don’t know the specific situation. It’s just like what you learned* Learn some!
It is best not to use sodium carbonate, the reason: 1. Sodium carbonate is relatively easy to crystallize and will block the pipeline after being entrained by gas into the pipeline. If it is used as an accidental chlorine absorbent, it will agglomerate on the filler after long-term circulation water loss. 2. The absorption effect is not ideal. Sodium carbonate absorbs chlorine and releases carbon dioxide. If it is a tower type absorption, it will increase the fan load and affect the system pressure control. ； If it is okay to use chlorine gas to pass the sodium carbonate solution under positive pressure, it is recommended that the concentration not exceed 150g/L.
