1. Process Brief

Using ammonium nitrate and potassium chloride as raw materials, potassium nitrate and ammonium chloride are produced by double decomposition method. According to the phase diagram of ammonium nitrate, potassium chloride, potassium nitrate and ammonium chloride quaternary water salt system, reasonable process conditions are selected to control the composition of the reaction liquid, so that it is in the crystallization zone of potassium nitrate and ammonium chloride in turn, so as to achieve the purpose of separating potassium nitrate and ammonium chloride, After separating potassium nitrate and ammonium chloride, the mother liquor is supplemented with potassium chloride and ammonium nitrate for potassium nitrate crystallization and ammonium chloride crystallization respectively. In the production process of this method, the mother liquor is recycled without the discharge of three wastes. The product potassium nitrate and by-product ammonium chloride are widely used, which is an economic and environmental protection production process.
