摘　　要：为解决厂际间减压渣油热进料长距离输送至溶剂脱沥青装置存在的管道压降大、电耗高、管道散热损失大等问题,需要确定能耗低且投资及运行费用低的最优方案。本文通过对比不同规格管道的建设投资及运营期运行费用,求得年均总费用,综合分析提出管道输送工艺流程方案,进而达到节省投资、节能降耗的双重目的。本方法可以适用于厂际间及各类装置间热料输送管道优化设计,对类似项目管道系统工艺流程的确定具有参考和借鉴作用。In order to solve the problems of high pressure drop of piping,high power consumption and large pipeline heat dissipation loss in long-distance transportation of vacuum residue hot feed to solvent deasphalting unit between plants,it is necessary to determine the optimal scheme with low energy consumption,investment and operating costs.This paper compares the construction investment and operating costs of different specifications of pipelines to obtain the annual total cost.Through comprehensive analysis,a piping transportation process flow scheme is proposed to achieve the dual goals of saving investment and energy consumption.This method can be applied to the optimization piping design of hot material conveying between plants and various units,and it can be used for reference to determine the process flow of piping system in similar projects.
