摘　　要：采用火用分析方法对炼油厂常减压蒸馏装置能耗进行评价,建立了常减压蒸馏装置及各设备的火用分析模型,定义了火用效率、火用损率等评价标准。基于测试数据对装置各设备火用损失进行了计算。结果表明,常减压加热炉的火用效率较低,分别为41.5%和44.1%,常压炉、减压炉、常压塔、减压塔、换热器等设备的火用损率较高。Exergy analysis was used to evaluate the energy consumption for atmospheric and vacuum distillation unit in a refinery. The exergy analysis model was made for atmospheric and vacu- um unit and its devices. The evaluation standards of exergy efficiency and exergy destruction rate were defined. The availability destruction of different devices for the unit and devices was calcu- lated. The result shows that the exergy efficiency of atmospheric furnace and vacuum furnace is 41.5%and 44. 1% respectively. The exergy destruction rates of atmospheric furnace, vacuum furnace, atmospheric column, vacuum column and heat exchangers are higher.
