Distillation Yields from Blending Cabinda Crude Oil and Oman Crude Oil

Abstract

The blending optimization of Cabinda and Oman crude oil was investigated to provide a consistent and optimal feedstock to refinery operations. The distillation yields < 520°C and products' distribution were studied by equilibrium-fresh vaporization (EFV) method. The results revealed that the optimal blending ratio of Cabinda and Oman crude oil was 7:3, the distillation yield before 520°C was 73.90%, 3.87% higher than the theoretical distillation yield. Relationship of distillation yields, kinematic viscosities (50°C), and surface tension (25°C) showed that the change of kinematic viscosities and surface tension were contrasted with the change of distillation yield, and meanwhile, the diesel fraction output was comparatively increased during blending distillation.
