为使兰成渝成品油管道在增输不新增泵站设施的情况下,能够安全平稳的运行,在兰成渝管道广元—成都段进行了成品油减阻剂的工业试验,分别完成了柴油3个加剂浓度(5mg/kg、10mg/kg和15mg/kg)试验和汽油一个加剂浓度(15mg/kg)对比试验,试验过程包括3个不同基础流量(600m3/h、650m3/h和700m3/h)下的减阻试验、增输试验以及管道允许工况的最大输量试验;试验分析了管道流量、加剂浓度及剪切过程对减阻剂作用效果的影响以及加剂条件下管道的最大输送能力,得出了兰成渝成品油管道在一定减阻剂加量下的安全输量范围。
In order to ensure that Lancheng-Yu product pipeline can operate safely and steadily without adding new pumping station facilities, the industrial test of refined oil drag-reducing agent was carried out in Guangyuan-Chengdu section of Lancheng-Yu pipeline. Diesel fuel three additive concentrations (5mg / kg, 10mg / kg and 15mg / kg) test and a gasoline concentration (15mg / kg) comparative test, the test process includes three different basic flow (600m3 / h, 650m3 / h And 700m3 / h) drag reduction test, transmission test and pipeline maximum allowable conditions of the test; test analysis of the pipeline flow, the concentration of the additive and the shearing process on the effect of drag reducing agent as well as the additive conditions Under the maximum transmission capacity of the pipeline, come to Lan Cheng Yu product pipeline drag reduction in a certain amount of safety under the transmission capacity.
