OSTI ID:6568309
A crude oil composition having a low pour point is prepared by incorporating into a waxy crude oil an effective pour depressant amount of an oil-soluble terpolymer, such as vinyl acetate-ethylene-vinyl chloride or allyl chloride terpolymer. The terpolymer may be added with mixing directly to the heated crude or in hydrocarbon solution such as a solution of the terpolymer in a middle distillate or kerosene. In another aspect, this invention relates to a process for the pipeline transportation of the crude oil compositions previously described.
