摘要
介绍了磷酸的用途和磷酸生产的工艺路线,着重介绍了湿法磷酸工艺中的盐酸法及溶剂萃取净化磷酸技术的开发状况,并就每一种方法的优缺点作了分析。通过对不同的生产方法进行比较,并结合我国磷矿日益贫化、地区分布不平衡、能源紧缺及环境保护的要求,作者认为溶剂萃取盐酸法工艺是今后磷酸生产的发展方向。
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.
