The study focuses on the transportation of waxy oil in industrial pipelines, using pour point depressants to decrease pour point and increase fluidity for effective transportation. Through numerical methods, continuity, momentum, and energy equations were solved, and the theoretical analysis was verified with experimental data, confirming the effectiveness of pour point depressants for pumping waxy oil at temperatures below pour point.
Waxy oil transportation in the industrial pipeline becomes impossible at temperatures below pour point. Pour point depressant application allows transportation by decreasing pour point and increasing waxy oil fluidity. The novelty of the research lies in modeling waxy oil transportation with pour point depressant in the industrial pipeline. Randep-5102'' pour point depressant with a dose of 200 ppm is used for pumping of waxy oil. Continuity, momentum and energy equations with closing relations were solved by the numerical method. The verification of the theoretical analysis was carried out with experimental data measured by the SCADA (supervisory control and data acquisition) system sensors along the industrial pipeline length. The results of comparing thermo-hydraulic calculations with experimental data confirmed the effectiveness of pour point depressant for pumping of waxy oil at temperatures below pour point.
