Recycling and treatment of waste sulfuric acid in the silicone industry
Thread Content
Dear all: I have a question – during the preparation of silicone, to what extent does the concentration of concentrated sulfuric acid decrease after dehydration? How should concentrated sulfuric acid with reduced concentration be handled? Is it subjected to regeneration? If so, what will be its concentration after regeneration? What process should be used for regeneration? I earnestly ask the experts for their advice.
We should be able to provide assistance, mainly with the concentration of sulfuric acid to over 96%
I work in the silicone industry as well, and I’ve encountered the same problem. Could you please let us know if you can solve it, and if so, could you share the general approach? My email is renboyc@163.com
In the process of sulfuric acid dehydration, the concentration usually drops from 98% to 85%; it is possible to simply concentrate it to 93% and proceed with further dehydration cycles, though the amount of water removed will be less compared to using 98% acid.

The SAC vacuum concentration process can be used for concentration, enabling it to reach 95% concentration before being recycled back to the drying section
Our company’s dilute sulfuric acid concentration unit for the drying of caustic soda and chlorine gas has now been successfully put into operation
