METHOD OF PRODUCING POTASSIUM SULFATE AND PLANT FOR ITS EMBODIMENT Russian patent published in 1999 - IPC

Abstract RU 2124477 C1

FIELD: methods of production of potassium sulfate. SUBSTANCE: method for production of high-grade potassium sulfate from potash includes hydrochemical conversion of its solution with sulfuric acid. The method is realized in open-type reactor with conical bottom. Reactor is provided with device for circulating mixing of produced suspension with continuous metering of sulfuric acid to reactor. The process is ended in classification and filtering. EFFECT: production of pure large-crystalline potassium sulfate suitable not only as fertilizer free of chlorine but also for industrial chemical application. 2 cl, 2 dwg
