Potassium carbonate production methods
Potassium carbonate production methods Electrolysis is obtained by electrolysis of potassium chloride solution of potassium hydroxide, carbon dioxide in the carbonation carbonation tower. After evaporation of multi-effect evaporator, filtered potassium bicarbonate, and then calcined product were. This method is easy to get because of raw materials, utilization of high potassium, no waste produced and widely used, but more power. Ion-exchange method using cation exchange resin is exchanged with potassium chloride. Potassium bicarbonate, ammonium bicarbonate and then eluted into a dilute solution, the multi-effect evaporation, carbonation, crystallization, separation, calcination the products. This method is the product of good quality, short process for small-scale production. |
