Evaluation of the Effectiveness of Anti-Turbulence Additives in the Transportation of High-Viscosity Oil at Low Ambient Temperatures

This article investigates the effectiveness of using anti-turbulence additives (ATAs) to reduce hydraulic resistance during the pipeline transportation of high-viscosity oil. This study focuses on analyzing the impact of ATA dosage on the pressure loss and oil flow rate under turbulent flow conditions. Experiments demonstrated that a 40 g/t ATA concentration reduces hydraulic resistance by 25.1–36.7%, increasing pipeline throughput by ~60% (from 179.9 t/h to 289.8 t/h). This efficiency eliminates the need for constructing additional pumping stations, reducing capital costs by an estimated USD 5–7 million per 100 km of pipeline. Graphs confirm a nonlinear relationship between ATA dosage and pressure loss reduction, with optimal efficiency observed at 40 g/t. The findings emphasize the need for developing a comprehensive model that accounts for the physicochemical properties of the oil and additives, as well as the influence of flow parameters. These results provide a foundation for further research and the industrial application of ATA.
