摘　　要：从整个系统的角度出发对常减压装置换热网络进行优化,在保持换热终温不变的基础上,省出常减压换热网络的工艺物流,用作其他装置热源,进行和其他装置的热联合改进。结果表明,该方法节能效果十分明显,改造后可节约其他装置蒸汽消耗6.0 t/h,且涉及到的调整较小,在工程上更易实现。因此,采用系统分析方法,可以很好地降低全厂的能耗。Optimize the heat exchanger network of atmospheric and vacuum distillation unit from the whole system angle.Based on unchanging the end temperature of heat transfer,the process streams of atmospheric and vacuum distillation unit are saved to be used as heat source of other units.The results show that the energy-saving efficiency of this method is obvious and 6.0 t/h of the steam consumption for other units can be saved,and the adjustment is smaller.The energy-consumption for the whole plant can be saved by using the system analysis method.
