| Abstract: | Some technological features of AP plant's extending capacity from 90 kt/a to 120 kt/a designed by Sichuan Designing Institute of Chemical Industry and Yinshan Chemical (Group) Stock Ltd. are introduced , including the MAP process of extraction with double tanksslurry concentration with double effect and three body evaporatorhot air by flue gas exchange and other new technologies. Running in 2 000 , the plant has reached its design capacity with maximum output of 487 t/d MAP through test. The problems are also presented of the capacity match with supplementary equipment and the manufacture of domestic largescale reduction gear. |
