SYSTEMS AND METHODS TO PRODUCE POTASSIUM SULFATE. |
| abstract |
Systems and methods for producing potassium sulfate may involve converting a mixed-salt feed stream to a final conversion slurry in a conversion unit, the mixed-salt feed comprising at least one potassium-containing salt, at least one containing chloride, at least one magnesium-containing salt and at least one sulfate-containing salt and the final conversion slurry comprising schoenite; separating the final conversion slurry into a final conversion solids stream and a conversion brine; leaching the final conversion solids stream in a crystallization unit to produce a potassium sulfate product stream comprising potassium sulfate and a crystallizer mother liquor comprising magnesium sulfate and potassium sulfate; collect the heat generated in the conversion unit by means of a heat pump; and providing at least a portion of the collected heat to the crystallization unit to regulate a temperature of the potassium sulfate product stream and the crystallizer mother liquor stream contained in the crystallization unit. |
