Electrodialysis in the separation of Sulfuric acid from the mixture of Sulfuric and Hydrochloric acid

Chemical Engineering

Sulfuric acid has a wide array of applications in chemical industry. Most of the chemical industries produces acidic effluent, from which the acids must be recovered. Recovery of valuable acids leads to economic operation and safer disposal of waste. For recovery, many technologies can be used by which acids can be regained as such or can be converted into other value-added products. Membrane processes are being researched academically and practiced industrially. Ion-exchange membranes are used for many commercially relevant processes such as in electrodialysis and diffusion dialysis.
