摘要： A method of transporting waxy crudes through conduits at reduced friction and preventing wax separation or precipitation so as to inhibit plugging and flow restriction and improve the pour point properties of the crude by adding to such waxy crudes a small amount of a polymeric material containing aliphatic hydrocarbon side chains of at least 14 carbon atoms. This invention relates to decreasing friction loss in flowing waxy crudes through conduits, generally over great distances but also over short distances such as in well fracturing processes and also to improving the pour point of waxy crudes. More particularly, the invention is directed to crude oil compositions comprising a waxy crude oil and fractions thereof and polymers having aliphatic hydrocarbon side chains with at least 14 carbon atoms, so as to reduce the pour point, prevent wax separation and reduce its friction loss due to flow through pipelines over great distances and short distances.
