Liquid-liquid flow in the pipeline transportation system can consume large energy due to high frictional drop which can be decreased by adding some chemical additives. The effect of these additives is different from type to type and most of them used only for single phase flow. This work focuses on reducing the pump energy requirements of two-phase flow (oil–water) by using three types of additives, anionic surfactant (sodium lignosulfonate (SLS)), cationic surfactant (hexadecyltrimethylammonium bromide (CTAB)) and titanium nanoparticles. An energy analysis in case of varying the type of additives, mixture velocity, and oil fraction are presented.

The results showed that the power consumption is reduced significantly and maximum reduction (84%) was gained by using CTAB. The results also confirm that less value of oil fraction is required to phase inversion point after using CTAB, while SLS and nanoparticle cause an increase in the required value of oil fraction.

管道运输系统中的液-液流动会因摩擦力下降而消耗大量能量，而摩擦力下降可通过添加一些化学添加剂来降低。这些添加剂的效果因类型而异，并且大多数仅用于单相流。这项工作着重于通过使用三种类型的添加剂（阴离子表面活性剂（木质素磺酸钠（SLS）），阳离子表面活性剂（十六烷基三甲基溴化铵（CTAB））和钛纳米颗粒）来降低两相流（油水）的泵能量需求。给出了在改变添加剂类型，混合速度和油分的情况下的能量分析。

结果表明，使用CTAB可以显着降低功耗，并最大程度地降低功耗（84％）。结果还证实，使用CTAB后，相变点所需的油分值较小，而SLS和纳米颗粒会导致所需的油分值增加。
