摘　　要：通过工艺模拟和计算分析,对环己酮热回收系统的操作控制温度进行了优化,降低了系统的能耗和粗醇酮用量。选用具有更高通量和更高传质效率的新型固定阀悬挂式降液管塔板(DJ-5型专利塔板)替代原塔中的DJ-2型多降液管塔板和鲍尔填料,通过只新增1塔、改造2塔的方案使环己酮生产能力从30kt/a扩能到50kt/a,各项工艺指标均满足生产要求。该系统的成功改造为其他系统的改造提供了参考。The controlling temperatures of cyclohexanone heat recovery system were optimized by flowsheeting and analysis, which reduced the consumption of energy and the circulation of cyclohexanone. DJ -5 tray which had characteristics of high separation efficiency and large capacity was used to replace the original DJ-2 tray one for one. After reforming, the capacity was increased from 30 kt/a to 50 kt/a cyclohexanone by build one new column and reforming two old column, and all the quality index were satisfied. The success of the reforming provided a good reference for the optimization of other systems.
