摘　　要：分析了引进的AZF工艺尾气处理系统原设计存在的问题,将原单塔单器处理流程改造为双塔双器处理流程并进行进一步的优化。改造后,不仅提高了造粒尾气的氨回收率,减少了污染物排放量,而且简化了流程,取得了较好的经济和社会效益。The problems are analyzed in the original design of the tail gas treatment system based on the AZF Process introduced from abroad, and the original single column-single vessel treatment flow sheet is replaced by dual column-dual vessel flow sheet, with further optimization. After the renovation, not only is the recovery of ammonia from the granulation tail gas improved, the discharge of pollutants reduced, but also the flow sheet is simplified, resulting in better economic and social benefit.
