编号：T990490该工艺是将传统的重过磷酸钙生产方法与料浆法磷铵生产工艺结合在一起，在湿法磷酸氨中和制取磷铰料浆之前，加人磷矿粉，充分利用含硫酸量较高的湿法磷酸的高位化学能分解磷矿，从而大幅度降低磷铵产品的硫酸单耗（下降5％－15％），同时可降低磷铰产品的氨耗， Code: T990490 The process combines the traditional method of production of heavy superphosphate with slurry ammonium phosphate production process. Before wet phosphorus ammonium phosphate and phosphorus retentate slurry, add phosphate rock powder to make full use of High chemical capacity of wet-process phosphoric acid, which contains a high amount of sulfuric acid, can decompose phosphate so as to drastically reduce the sulfuric acid unit consumption (5% -15%) of the ammonium phosphate product and reduce the ammonia consumption of the phosphorus-
