Process for producing potassium sulfate from sodium sulfate |
| abstract |
There is disclosed a process for producing a potassium sulfate electrochemically. The process involves the use of sodium sulfate which is electrolyzed in an electrolytic cell (1) and which results in the production of sodium hydroxide and ammonium sulfate. The process carried out in a two or three-compartment electrolytic cell (1) and the ammonium sulfate is converted by ammoniation (20) and treatment of the ammoniated mixture with potassium chloride (22) to produce potassium sulfate. Potassium sulfate may then also undergo electrochemical treatment to produce potassium hydroxide and ammonium sulfate. |
