介绍以湿法磷酸和碳酸氢铵为原料连续生产磷酸一铵的工艺流程、主要设备;比较碳酸氢铵代替液氨生产磷酸一铵的优缺点,两种工艺应根据具体情况选用。 This paper introduces the process and main equipment of continuous production of monoammonium phosphate using wet-process phosphoric acid and ammonium bicarbonate as raw materials. The advantages and disadvantages of ammonium bicarbonate instead of liquid ammonia in producing monoammonium phosphate are compared. The two processes should be selected according to the specific conditions.
