| Abstract: | The phosphoric acid plant in Luzhai Fertilizer Co.[KG-*4],Ltd. with the dehydrateprocess of USA Barger has reached the designed capacity of 120 kt P_2O_5/a. However the recovery rate of phosphorus is only 85%. The affecting reasons are analyzed from raw material treatment, reacting system and filtrating system and the corresponding measures are presented. After the technological improvement, the recovery rate of phosphorus is increased to 92.7%. The consumption of phosphate rock is reduced by 18 570 tons per year, with 4 828 000 RMB Yuan saved. |
