Concentration of stannous chloride hydrochloride solution
Thread Content
An aqueous hydrochloric acid solution of about 15%, containing stannous chloride. I want to concentrate and remove about 3/4 of the excess water. The volume of the solution is 10 cubic units. Everyone, please help figure out what processes and equipment to use. It is best if the hydrochloric acid can be recycled (with a concentration of 30% being ideal)
Separation of hydrochloric acid from stannous chloride — nanofiltration process; Concentration of hydrochloric acid solution — evaporation process.
Has anyone done a similar process? You can add me on QQ at 550330717. This project can be done for you or completed as a paid service
Can a nanofiltration membrane withstand such strong hydrochloric acid? It shouldn’t be possible, I remember that nanofiltration membranes require a pH below 1.
I remember there being diffusion dialyzers used to treat pickling waste acid from steel plants, which contained impurities such as iron.
There are at least 5 types of acid-resistant nanofiltration products, and more than 10 years ago Baosteel installed a nanofiltration purification system for pickling solutions. Diffusion dialysis can also be used for salt separation, but no large-scale installations have been reported.
Can it withstand such high concentrations of hydrochloric acid?
