Production Method: Electrolysis Utilising Membrane Cell technology
Step1: Potassium Chloride added in water (saturated solution)->stir for more than 10 minutes;
Step2: dehydration, put mixed material (saturated solution) into the centrifuge for dehydratio->Part of the dehydrated mother liquor (about 4/5) enters the "concentrated crystallization" process.
Step3: Dehydration of mother liquor (about 4/5) of dehydration in the concentration kettle and concentrates, and potassium chloride mother liquor crystallization goes out potassium chloride crystal by concentration kettle, concentration pressure P <-0.05Mpa; Concentration time t >2h; Concentration temperature > 40°C; Blowing when concentrated to a large amount of crystals, the material enters the "dehydration" process.
Step4: Put the material in the concentrated crystallization process into a centrifuge for dehydration, and the dehydrated material enters the "stirring (1 time)" process cycle.
Step5: The processing of potassium chloride raw material has been completed, and the subsequent process is to produce potassium hydroxide by Electrolysis Utilising Membrane: 2KCl+2H2O==2KOH+H2+Cl2
