FLOXS减阻剂在格拉管道的应用试验

Test of FLOXS drag reducer ih the application of Gela Pipeline,

在格拉成品油管道上对局部管段进行了FLOXS减阻剂的应用试验。通过对这次试验数据的对比分析,指出该成品油管道注入FLOXS减阻剂减阻效果十分明显,可关闭中间泵站、减少注入站运行设备;但在各阀门处尤其是闸阀、弯管等都会对减阻剂有不同程度的剪切,影响其减阻效果。建议在今后全线加剂输送中改原设计越站流程诸多弯管为直管段和加球阀。

Application test of FLOXS drag reducer in partial section of Gela Oil Product Pipeline has been carried out. Through comparison and analysis on testing data, it is pointed out that an evident drag reduction result is obtained, meanwhile closing intermediate station and reducing the running equipment at injection station; but varying degrees of shear exists at valves, such as gate valves and bends, which effects on drag reduction result. The article also put forward a proposal that straight pipe section and spherical valve shall be equipped at the points with bends in the design of non-heating operation process for overall pipeline depressant transportation in the days to come.
