成品油管道不定分支运行计划编制方法的探讨

Discussion on the Operation Plan of Oil Product Pipeline with Indefinite Branches

针对不定分支成品油管道运行方式多样,工况调整频繁,对运行计划编制要求较高的问题,结合成品油管道运行计划编制经验,从工艺和优化两个方面提出了运行计划编制中需要注意的问题。在工艺方面,要注意流量和压力的限制条件;在优化方面,要注意混油量的控制,合理安排油品输送顺序,控制好混油流速,作好运行能耗的控制以及市场与油库的匹配。提出了轮流运行、提前调整分输比例以及更换铺底油品的运行计划编制的思路和一些根据实际情况灵活安排输送计划的方法。

In view of the problems of various operation modes, frequent adjustment of working conditions and high requirements for the preparation of operation plans for oil product pipelines with indefinite branches, and combining with the experience of the preparation of operation plans for oil product pipelines, the problems needing attention in the preparation of operation plans from two aspects of process and optimization are put forward. From the aspect of process, the restriction conditions of flow rate and pressure should be concerned;from the aspect of optimization, the transmix quantity and flow rate should be controlled, the transportation sequence of oil products should be arranged reasonably, the control of energy consumption and the match of market with oil depot should be improved. The idea of working out the operation plan of oil product pipeline with indefinite branches is put forward, such as alternate operation, adjusting the proportion of distribution in advance, and replacing the bottom oil products.
