摘要: 为研究顺序输送成品油管道混油在T型管处的分输问题,应用多相流模型,将90#汽油与0#柴油作为交替输送对象,建立了顺序输送混油控制方程。对汽柴油在不同输送顺序下形成的混油通过支管下载的过程进行数值计算,得到了混油量分布情况,分析了输送顺序不同时分输部分干线中混油对混油段的影响。结果表明,对干线管道中的混油通过沿线所设站场进行适量下载等混油处理,可显著缩短混油管段长度,减小管道末站对混油段下载的压力。

Abstract: In order to study the problem of distribution of mixed oil in T-shape pipeline of refined oil products. And the control equation of the sequential transport mixed oil is established by using multiphase flow model, 90# gasoline and 0# diesel are used as the alternate transportation objects. The process of downloading the mixed oil formed by gasoline and diesel under different conveying sequences through the branch pipe is numerically calculated, and the distribution of mixed oil quantity is obtained. The influence of the mixed oil in the main line on the mixed oil section under different conveying sequence is analyzed. The results show that the mixed oil in the main pipeline can be shortened by the appropriate amount of oil in the station provided along the line, which can significantly shorten the length of the mixed oil section and reduce the download pressure on the mixed oil section of the pipeline at the end station.
