Low pour point crude oil compositions
Patent
·
OSTI ID:5234504
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 polymer, such as vinyl acetate-ethylene-propylene or butylene terpolymer or a graft copolymer in which propylene or butylene is grafted onto an ethylene-vinyl acetate copolymer backbone or basic chain. 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.
