Lube oil from blends of Nigerian Escravos light and Agbabu bitumen by empirical modeling

摘要

Blends of Escravos light crude and Agbabu bitumen were prepared, distilled and characterized to investigate the effect of the blending on the yield and properties of the distillation fractions. The specific gravity, sulfur content, pour point and flash point of the blends were dependent on the proportions of the components. Regression analysis of the yields of distillation fraction gave robust empirical models. The predicted optimal blend of equal amounts of Escravos and Agbabu bitumen gave distillation fractions similar in properties and yield to the Russian Urals crude. Light components from the Escravos played enhanced solubilization of the heavier components in the bitumen.
