| titleOfInvention | Co-production of potassium sulfate and sodium sulfate |
| abstract | A process for producing potassium sulfate or potassium sulfate and sodium sulfate from potash (10) and a sodium sulfate/water source (46 and/or 76), which includes: (a) subjecting a sodium sulfate source (46 and/or 76) to conversion with potash (10) in an aqueous medium to yield glaserite precipitate (20) and a first mother liquor (26); (6) converting the glaserite precipitate (20) with potash (10) and water (18) to produce a potassium sulfate precipitate (52) and a second mother liquor (40); (c) returning the second mother liquor (40) to step (a); (d) evaporating the first mother liquor (26) such that a sodium chloride and anhydrous sodium sulfate solids mixture is precipitated in a third mother liquor (28); (e) subjecting the solids from step (d) to a sodium sulfate/water source (12) to produce anhydrous sodium sulfate; and (f) returning the third mother liquor (28) for conversion to potassium salts. |
