Sweeney, W M

A low pour point residual fuel oil composition is prepared from a major amount of a high pour point, low sulfur, waxy, residual fuel and a minor amount of a low wax, low pour, residual fuel oil by adding thereto from 0.01 to 0.5% by weight of an oil soluble terpolymer such as vinyl acetate-ethylene-propylene or butylene or a graft copolymer in which propylene or butylene is grafted onto an ethylene-vinyl acetate copolymer backbone or basic chain, having preferably, a number average molecular weight of about 12,000 to about 60,000. In another aspect, this invention relates to a process for the pipeline transportation of the low pour residual fuel oil compositions previously described.
