| Abstract: | The quality of dilute phosphoric acid affects the quantity nutrient in powdery monoammonium phosphate products. The control method of nutrient in the monoammonium phosphate product is described from the view of the production, according to the fluctuation of dilute phosphoric acid composition, acid concentration,specific gravity and the solid content. Finally,the qualified product can be produced stably by adjusting neutralization degree of slurry, product moisture, ratio of concentrated phosphoric acid or monoammonium phosphate slag slurry,first-effect evaporator slurry density and so on. |
