Does anyone know the main component of ammonia II mud in the process of preparing soda ash by the combined alkali method?
Thread Content
The combined alkali production method includes two processes: The first process is the same as the ammonia-alkali method. Ammonia is passed into saturated brine to form ammonia salt water, and then carbon dioxide is introduced to form sodium bicarbonate precipitate. After filtration and washing, NaHCO3 tiny crystals are obtained, and then calcined to obtain a soda ash product. The filtrate is a solution containing ammonium chloride and sodium chloride.
We do not recycle ammonia 2 mud. I think it might be tiny crystals of ammonium chloride, and some entrained salt. Add some sulfide.
Has anyone tested its specific ingredients?
Mainly: Calcium and magnesium ions account for 10%, mud accounts for 80%, the remainder is ammonium chloride, which accounts for 5%, and the rest is sediment!
It is mainly calcium and magnesium ions, with a small amount of sediment, NH4CL, NaHCO3, NaCL, and NH3.H2O. The ingredients are very complex; in fact, the most important thing is to know how to handle AII mud. This is something that makes many factories waste their brains. If you have good suggestions, please tell me!
