摘　　要：分析了歧化装置能耗较高的原因。将甲苯塔的筛板塔盘更换为ADV高效浮阀塔盘,降低工艺用能,并取得了很好的分离效果;将反应进出料换热器更换为高效的板壳式换热器,充分回收反应热;通过优化流程和增加热高分,充分利用热高分罐底出料和汽提塔底料能量,降低了反应出料空冷和水冷的冷却负荷。装置直接降低能耗12.3千克标油/吨原料。The causes of high energy consumption of toluene disproportionation unit were analyzed. Energy consumption was remarkably reduced after application of ADV high efficiency valve tray, installation of high-efficiency lamella heat exchanger for reactor feed and effluent, and addition of hot high pressure separations. As a result, a decrease of 12.3kg of oil equivalent per ton of feedstock over its energy consumption was obtained.
