THE EFFECT OF ADDITIVES ON POUR AND RHEOLOGICAL PROPERTIES OF 650 DEG F FRACTION OF CRUDE OILS AND THEIR BLENDS; ITS RELATIONSHIP TO COMPOSITION

Initial studies carried out with Enjay Chemical Co.'s ester copolymer ECA 4242 additive and low-sulfur, waxy, high-pour residual fuels from three Libyan and one West African crude oil showed that it is cheaper to lower the viscosities and pour points of non-Newtonian residual fuels with additives at the 0.1-0.3% by wt level than to remove the solids; the additive-containing oils behave rheologically like the dewaxed material, i.e., they are almost Newtonian; the lower the total solids and the paraffin content of the fuel, the more responsive it is to additive treatment as measured by the point lowering; and a residual fuel unresponsive to additive treatment can be effectively treated with additives when it is diluted with low-solids stocks.
