| Abstract: | The uses and production process of phosphoric acid were introduced. Especially the hydrochloric acid method and the technique status of solvent extraction and purification of phosphoric acid in wet phosphoric acid production process were introduced. The advantages and disadvantages of each process were analyzed. Through the comparison of different production methods, combined with the status of decrease of the content of phosphate rock, its distributing imbalance, energy crisis and environment worsening, authors think the solvent extraction and purification of phosphoric acid produced with hydrochloric acid method is the development direction in future. |
