Self-Incompatible Crude Oils and Converted Petroleum Resids

Self-incompatible oils are those containing insoluble asphaltenes that were not formed by mixing incompatible oils. Three refinery examples are given of self-incompatible oils: self-incompatible crude oils, thermally cracked oils, and oils hydrotreated with size selective catalysts that convert resi...

Description
Summary:Self-incompatible oils are those containing insoluble asphaltenes that were not formed by mixing incompatible oils. Three refinery examples are given of self-incompatible oils: self-incompatible crude oils, thermally cracked oils, and oils hydrotreated with size selective catalysts that convert resins relative to asphaltenes. Methods are presented for using the oil compatibility model and tests to detect self-incompatible oils and to mitigate the fouling caused by the insoluble asphaltenes.
