Regarding the control of multi-substance reaction crystallization, please ask the masters and experts for advice! I am doing a reaction crystallization experiment using phosphoric acid, urea, ammonium chloride, potassium chloride, and ammonium bicarbonate for reaction crystallization. The required crystal content is 20% nitrogen, 10% phosphorus, and 15% potassium! Contact QQ844074745 Email: gxly2277@163.com Thanks!
Generally, the slurry is processed first, and then sprayed and granulated. If crystallized directly, the yield will be relatively low.
We're asking for something crystalline!
This is compound fertilizer. According to the production of compound fertilizer, it is probably about the same.
It is recommended to consider the aspect of potassium ammonium dihydrogen phosphate. It is estimated that it is difficult to solve the problem by simple crystallization. Phosphoric acid and ammonia (potassium) can generate ammonium dihydrogen phosphate (potassium), continued neutralization can generate diammonium hydrogen phosphate (potassium), and further neutralization can generate triammonium phosphate (potassium). First use phosphoric acid and ammonia to prepare ammonium dihydrogen phosphate, and then neutralize it with potassium hydroxide. By controlling the pH, the product of potassium ammonium phosphate is obtained.
