摘　　要：飞达化工公司在尿素生产流程中，使用脱碳闪蒸气（ＣＯ２≥７０％）、合成氨和三聚氰胺回收的浓氨水（含ＮＨ３１８％～２２％），调整部分工艺指标，利用原碳化装置，实现联产碳铵，取得了明显的经济和社会效益。The urea technological process of Feida Chemical Co. is presented. It utilizes the flash gas from CO 2 removal (CO 270%),ammonia, the concentrated aqua ammonia (containing 18%～22% of NH 3) recovered from the melamine plant and the existion ammonium bicarbonate unit to coproduce ammonium bicarbonate by readjustment of some of the process indices, with remarkable economic and social benefits.
