Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
