摘　　要：介绍尿素合成塔的基本要求、结构、流程及反应原理,分析尿素合成塔塔盘改造前系统存在的问题,对比改造前、后尿素合成塔的性能特点、运行参数。通过对尿素合成塔的塔盘改造,尿素日产能可增加约205 t,吨尿素蒸汽单耗减少约0.05 t,吨尿素氨耗由0.571 t降至0.568 t,改造取得较好效果。The urea synthesis tower and its basic principle,structure,process flow and the reaction mechanism were described.The problems existed before the reformation of the tray were analyzed,and the performance and operation parameters before and after the reformation were compared.After the reformation,the urea output per day increased about 205 t,steam consumption per ton urea reduced about 0.05 t,ammonia consumption per ton urea reduced from 0.571 ton to 0.568 ton.
