Abstract: The stability of an oil-based fluid crude oil fluid may be determined by measuring a first RI value of the crude oil that does not comprise a solvent where the first RI value is used to determine a first solubility parameter therefrom. A second RI value may be taken from the crude oil at a point of asphaltene flocculation during a turbidimetric flocculation titration. The second RI value may be used to determine a second solubility parameter. A process for refining the crude oil may be controlled by maintaining the process or implementing a change to the process based on a ratio of the first solubility parameter to the second solubility parameter.

Abstract: A process for refining crude oil can be controlled to mitigate fouling by deploying a refractive index probe at a location suitable for making a crude oil stability determination, wherein the crude oil stability determination is relevant to controlling the refining process; making a measurement of crude oil stability; and then controlling the process for refining crude oil by maintaining the process or implementing a change to the process, based upon the determination of crude oil stability. This concept can also be applied to transporting, blending, and storing crude oil.
