Do the True Boiling-Point Distillation Yields of Crude Oil Blends Obey the Additive Blending Rule?

Twelve crude oil blends prepared from seven individual oils and an imported atmospheric residue were characterized through a true boiling point (TBP) distillation analysis their density. When comparing the measured TBP fraction yields with those estimated application of additive blending rule, it was found that, for four blends, rule valid, while remaining eight deviations ones bigger than analysis’s repeatability limits. By use intercriteria evaluation data deviation molar excess volume statistically meaningful relations between delta light heavy naphtha, as well vacuum volume, found. The higher magnitude blend’s naphtha are. behavior that regular solution, quantified by
