Effect of impurity on phosphoric acid and phosphate ammonium productions and its control measures |
| |
| Abstract: | The effects of calcium oxide,sesquioxide,magnesium oxide,potassium oxide,sodium oxide,and acid non-soluble substance in phosphate rock on production process of phosphoric acid,and effects of magnesium and fluorine in phosphoric acid on the production of phosphate ammonium,as well as effects of metal ions in phosphoric acid on quality of phosphate ammonium products are elaborated.The control measures corresponding to these influences are introduced including a series of physical and chemical methods to purify the impurities,which can make the product quality conforms to the standard. |
