| Abstract: | Adjusted brine with carnallite crystallizing point pump to the plant where it reaction with brine with bischofite crystallizing point, create carnallite containing a little sodium, then water added, decompose, remove magnesium chloride in the room temperature without carnallite process step in the salt pan.
To design flowage structure through introduce theory for control rate of decomposition and crystallization, process mirabilite and potassium chloride in the new - style crystallization reactor with internal circulation installation for crystallization, classification, impurities separation are carry through simultaneously in mother liquid circulation to produce potassium sulfate in high quality. |
