Potassium chloride saline finishing agent consumption

What are the consumption amounts for barium chloride, potassium carbonate, ferric trichloride, and potassium sulfite? # hcbbs

The amount of barium chloride required depends on the target level of sulfate in the brine; I would estimate it to be around 1.5 KG of barium chloride per cubic meter of brine. For potassium carbonate, the amount depends on the calcium and magnesium content in the raw salt, with approximately 1.25 KG per cubic meter of brine. As for potassium sulfite, the amount isn’t fixed – more is added if the free chlorine level is high, less if it’s low, and none at all if there’s no free chlorine. Why isn’t the consumption of potassium hydroxide being asked about? Hehe
3# lujianfei79: Your salt consumption efficiency must be quite poor. Barium chloride requires 16 Kg per ton at 100% alkali concentration, while potassium carbonate needs 8 Kg per ton at 100% alkali concentration. What do these figures say about your efficiency?
The quality of the raw salt is indeed not very good; the salt sludge is quite dirty. But after doing some calculations, I found that the amount you mentioned is even higher than the amount I specified. The amount of potassium carbonate I suggested is only around 5 KG per 100 units of alkali. 4# quhong*ng80
