文章针对惠州炼油1200万吨／年常减压装置运行第一周期能耗偏高原因进行了分析，主要原因就是装置原油偏离设计，加热炉空气预热器不适应长周期操作和能耗管理有偏差，并就原因提出优化措施：改造装置、更换空气预热器以及精细化能耗管理，在装置第二周期运行阶段，装置能耗明显降低。

the paper analyzed the reason that the energy consumption is much higher than the designed one during the first period of cdu of the Huizhou refinery with twelve million ton per years. The reason mainly depend on the property deviation of feedstock, incorrect air pre-heater and energy consumption manage. The cdu unit has been revamped, changed better pre-heater, and managed energy consumption in detail, so during the second period of cdu unit the energy consumption has been decreasing obviously.

常减压，能耗，优化，cdu： energy consumption，optimization。
