Concentrate dilute sulfuric acid
Thread Content
This post was last edited by sunjl1981 on 2013-1-6 20:29. The chlor-alkali industry uses 98% concentrated sulfuric acid as the drying medium in the chlorine drying process. When the sulfuric acid concentration is lower than 75% or even higher, it is treated as waste acid. Could you please give me some advice on which technology should be used to concentrate sulfuric acid so that it can be reused? Is there any economic benefit? # , , &

It is more suitable to use multi-effect plate evaporation. I wonder if your company is still considering this aspect. If so, please contact me at 15195980636 Li Yangde
