Turbulent Drag Reduction in Oil Pipelines Using Mixed Surfactant and Polymer Additives

在石油和其他工业中，减少管道流动的阻力是一个非常重要的问题。当像油这样的流体在管道中流动时，由于流体中的摩擦，机械能会发生显著的耗散。由于泵的功率消耗以及与泵送流体相关的成本与管道系统中的摩擦能损失直接相关，因此减少摩擦能损失是非常可取的。减少管道流动中摩擦能量损失的最佳替代方案之一是使用减阻添加剂，如某些类型的聚合物和表面活性剂。在流体流动中加入少量添加剂可以显著降低摩擦系数，提高管道容量。减阻添加剂，特别是表面活性剂，也有助于减少管道的腐蚀。该研究工作将探索在聚合物-表面活性剂混合添加剂的帮助下，通过减少摩擦/阻力来降低泵送能量需求的方法。所提出的研究的重点是发现和探索混合聚合物和表面活性剂添加剂对减阻的协同作用。在完成拟议的研究后，将建议将碳氢化合物液体泵送成本降至最低的策略。这项研究将对加拿大管道公司降低碳氢化合物的泵送成本非常有益。

Drag reduction in pipeline flows is of great interest in petroleum and other industries. When a fluid such as oil flows in a pipeline, there occurs a significant dissipation of mechanical energy due to friction in fluid. As the power consumption of pumps, and hence the cost associated with pumping of fluids, is directly related to the frictional energy loss in a pipeline system, the reduction of frictional energy loss is highly desirable. One of the best alternatives to reduce the frictional energy loss in pipeline flows is to use drag-reducing additives such as certain types of polymers and surfactants. The addition of a small amount of an additive to fluid flow can reduce the friction factor and increase the pipeline capacity significantly. The drag reducing additives, especially surfactants, are also helpful in reducing corrosion of pipelines. The proposed research work will explore ways to reduce the pumping energy requirements by reducing friction/drag with the help of mixed polymer-surfactant additives. The thrust of the proposed research is to discover and explore synergistic effects of mixed polymer and surfactant additives on drag reduction. Upon completion of the proposed research, strategies will be recommended to minimize the cost of pumping hydrocarbon liquids. The proposed research will be highly beneficial to Canadian pipeline companies in reducing the pumping costs of hydrocarbons.
