Adaptation of Mathematical Models for the Determination of Crude Oil Blends Stability

Abstract

Crude oil blend formulation has been topical in recent times with research focus on yield maximization by appropriate feedstock preparation. The present work developed a simple mathematical algorithm to predict with precision, asphaltene precipitation as measure of crude oil blend stability and compatibility. Crude oil Blend stability was measured in terms of Colloidal Insolubility Index (CII), Asphaltene to Resin (A/R), ratio and ration of the Solubility Blending Number () and Insolubility Index (R). Results of the present work are in good agreement with plant data and simulation results of previous work for all parameters of blend stability determination. In each case, both studies gave stable blends as shown above. Main contribution of this work to the subject matter is in its unambiguous and precise nature, and its simplicity, both of formulation and application.
