| Abstract: | The pre-neutralization ＋ tubular reactor ＋ ammoniatorgranulator process is adopted in 240 kt/a DAP plant of Qinghai Yuntianhua International Chemical Co., Ltd., the operation of granulator is not ideal. Through the internal structure reformation of granulator, the amount of rubber plate is reduced, the utilizing rate of ammonia is increased to more than 70%, the operation ratio of granulator and quality of product are also improved greatly. |
