Regular solution based approach to modeling asphaltene precipitation from native and reacted oils: Part 2, molecular weight, density, and solubility parameter of saturates, aromatics, and resins

The molecular weight, density, and solubility parameter of the crude oil medium are inputs to regular solution based models for asphaltene precipitation. For native oils, these properties can be determined from a SARA (saturate, aromatic, resin, asphaltene) assay and existing correlations for each SARA component. However, thermo- and hydrocracking alter these properties and these changes must be accounted for when modeling the solubility of...
