CRUDE OIL COMPOSITION, IMPROVED METHOD FOR TRANPORTATION OF CRUDE OIL, AND METHOD FOR IMPROVING POUR POINT CHARACTERISTIC OF CRUDE OIL

摘要

A low pour point crude oil composition is prepared by incorporating in a waxy crude oil an effective pour point depressant amount of an oil soluble ethylene-acryonitrile copolymer or terpolymer. The copolymer or terpolymer is usually added as a solution. In one aspect the invention relates to the pipeline transportation of the low pour crude oil composition.
