摘　　要：针对尿素装置解吸水解系统在运行过程中存在的问题,分析其原因,并采用立体高效传质塔盘对解吸塔进行改造。改造后,解吸水解系统可在110%负荷下稳定运行,最高负荷可达135%;经解吸水解系统处理后的工艺冷凝液基本达到设计指标要求,可送至循环水系统回收利用。In connection with problems in operation of desorption and hydrolysis system of urea unit, the causes are analyzed, and the desorber is revamped with high efficiency combined trapezoid spray tray. After the revamp, the desorption and hydrolysis system can run stably under 110% load, and the highest load can reach 135% ; process condensate treated with desorption and hydrolysis system meets the requirements of design index basically, and can be recovered to circulating water system.
