Patent number: 9845434Abstract: Biological source oils, including, but not limited to, algae oil, stabilize the presence of asphaltenes in petroleum feedstocks, such as crude oil, to help avoid or prevent fouling and/or corrosion in the production, transferring and processing of the petroleum feedstocks. Chemical additives such as phenol-based resins, and reaction products or combinations of long chain alpha-olefins and/or small chain aldehydes and/or long chain alkyl phenate sulfides and/or metal oxide-based colloidal hydrocarbon-based nanodispersions, may also stabilize the presence of asphaltenes in petroleum feedstocks. By “stabilizing” is meant keeping the asphaltenes in solution in the petroleum feedstocks.Type: GrantFiled: December 19, 2016Date of Patent: December 19, 2017Assignee: Baker Hughes, a GE company, LLCInventors: Sai Reddy Pinappu, Lawrence N.

Patent number: 9581581Abstract: 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.Type: GrantFiled: April 17, 2015Date of Patent: February 28, 2017Assignee: Baker Hughes IncorporatedInventors: Marco Respini, Giuseppe Della Sala, Gavin M.
