介绍了 BEM 3原油流动性改进剂的合成方法及其在鲁宁线上的工业性应用情况。BEM 3是一种复合型的原油流动性改进剂 ,它具有长烷基链和极性基团 ,对原油具有较好的感受性和较好的降凝效果和降粘效果。现场试验表明 ,BEM 3对鲁宁线原油具有较好的降凝效果和降粘效果 ,鲁宁线应用 BEM 3原油流动性改进剂后 ,降低了管线安全运行温度 ,取得了可观的经济效益。
The synthesis method of BEM 3 crude oil fluidity improver and its industrial application in Luoning line are introduced. BEM 3 is a complex type of crude oil fluidity improver with long alkyl chains and polar groups. It has good sensibility to crude oil, better depressing effect and viscosity reducing effect. Field tests show that BEM 3 has good depressing effect and viscosity reducing effect on Luoning crude oil. After applying BEM 3 crude oil fluidity improver to Luoning Line, the safe operation temperature of the pipeline is reduced, and considerable economic benefits have been achieved.
