摘　　要： 探讨了炼油装置应对中间物流出料温度提高的能量优化策略,并将优化策略应用于某炼油厂常减压蒸馏装置与催化裂化装置的能量优化改造中。这些策略包括优化各装置工艺用能环节、优化调整换热网络以及装置间热集成,其目的是将炼油企业的节能降耗工作从单套装置推向全局系统,实现能量在全厂的综合优化利用。应用结果表明,上下游装置的能耗得到显著降低。由于中间物流实现直供,中间产品罐区的能耗和储运流动资金也得到降低。某案例的改造只需更换或新增换热器和管线,其投资为1014万元,而能获得的经济效益为2252万元/a,投资回收期少于6个月。 This paper presents the optimization strategies of energy utilization in refineries base on transferring high temperature intermediate streams between units, such as optimizing energy consumption of individual processing unit, properly adjusting heat exchange network and integrating the heat utilization among units. The aim is to impel energy saving from units to the whole system optimization. The proposed strategy was applied to one CDU and FCC unit modification case. The result shows that the energy consumption of upstream and downstream units is decreased. Because the intermediate stream is fed straightly, the energy consumption of intermediate product tank and circulating fund of the storage and transportation are reduced. Changing or adding heat exchanger and pipe-line is just needed in this revamping case. The total investment is 10.14 million RMB, but the economic benefit is 22.52 million RMB annually, thus the capital pay-off time is less than 6 months. It is demonstrated that the energy optimization base on transferring hot feed between units is a way of low input and high output, which is significance for the coming turn of energy saving.
