Please tell me about the process of co-producing sulfuric acid and sodium hydroxide through sodium sulfate electrolysis.

This post was last edited by txgyl on 2017-2-4 07:40. Some literature reports that the process of co-producing sulfuric acid and sodium hydroxide through sodium sulfate electrolysis can be used. Is this process currently used in production?
Don't any of the masters have anyone to give them advice?
This technology existed decades ago and has no future. It consumes a lot of electricity and the acid is too thin and impure. At present, the best concentrated sulfuric acid costs only a few hundred yuan per ton.
This project is theoretically feasible, but in practice it is unprofitable and can only stay in the patent stage at best.
To add, if it is a high-profit industry such as organic synthesis, and it is just for environmental protection issues, and you would rather lose some money to achieve recycling, the electrolysis method can still be considered. I have researched related fields for many years. For details, please contact myben@126.com
There is probably also a membrane in the middle, and it needs to withstand strong acids on one side and strong bases on the other.
Hello, what's your last name? How to contact you?
Sir, didn’t I give my email address in my reply post? Send an email to discuss in detail
Bipolar membrane is estimated to be feasible and the cost is relatively low
