Recently, the company has proposed a policy of energy conservation and consumption reduction, allowing our frontline employees to reduce raw material consumption. I would like to hear what countermeasures your company has to help me. I am very grateful! # hcbbs
According to the calcium and magnesium content in the brine, adjust the amount of sodium carbonate and sodium hydroxide, and control the amount of over-alkali at 0.3--0.6 g/L
Keep the amount of over-alkali to a low level, and the consumption will naturally decrease. However, the prerequisite is to ensure the quality of the brine, and do not reduce it blindly, otherwise the consequences will be serious. The amount of over-alkali in Na2CO3 should not be less than 0.3g./
When meeting the process indicators, add as little soda ash and caustic soda as possible.

I would like to hear the specific practices of your company.
The most important thing is to control the stability of 0.3-0.6 and the pass rate is more than 90%, which is more economical.
If possible, 0.1-0.3 sodium hydroxide can be used
The original poster: The redistribution sink should be easy to use, right? It will affect the balance of primary refined brine and may even cause parking problems. ； If this is the case, saving a little bit of alkali is not worth the loss.
