Patent number: 10994252Abstract: In at least one embodiment, the inventive technology relates to in-vessel generation of a material from a solution of interest as part of a processing and/or analysis operation. Preferred embodiments of the in-vessel material generation (e.g., in-vessel solid material generation) include precipitation; in certain embodiments, analysis and/or processing of the solution of interest may include dissolution of the material, perhaps as part of a successive dissolution protocol using solvents of increasing ability to dissolve. Applications include, but are by no means limited to estimation of a coking onset and solution (e.g., oil) fractionating.Type: GrantFiled: March 19, 2019Date of Patent: May 4, 2021Assignee: The University of Wyoming Research CorporationInventors: John F. Schabron, Joseph F. Rovani

Patent number: 10808183Abstract: The inventive technology, in at least one embodiment, may be described as a method of destabilizing an aqueous hydrocarbon emulsion comprising the steps of: effecting contact between a sorbent and said aqueous hydrocarbon emulsion; effecting relative motion between said sorbent and said aqueous hydrocarbon emulsion; and destabilizing (perhaps in continuous fashion) the aqueous hydrocarbon emulsion. Applications include but are not limited to oil spill clean up, manufacturing of emulsions, oil refinery and production operations (anywhere along the production chain).Type: GrantFiled: September 12, 2013Date of Patent: October 20, 2020Assignee: The University of Wyoming Research CorporationInventors: John F.

Publication number: 20200088709Abstract: At least one embodiment of the inventive technology may be described as a method for analyzing a hydrocarbon that comprises volatiles, said method comprising the steps of: segregating said volatiles from said hydrocarbon without oxidizing said hydrocarbon; generating a hydrocarbon residue and segregated hydrocarbon volatiles; and analyzing at least one of said hydrocarbon residue and said segregated hydrocarbon volatiles. The advantageous avoidance of oxidation may be achieved by placing the hydrocarbon under a vacuum, which may also enable the avoidance of cracking of the hydrocarbon while still achieving segregation of volatiles as desired. One other of the several embodiments disclosed and claimed herein may focus more on vacuum transfer and vacuum distillation of hydrocarbon volatiles. These and other methods disclosed herein may be used to achieve improved hydrocarbon analysis results.Type: ApplicationFiled: November 25, 2019Publication date: March 19, 2020Inventors: Jeramie J. Adams, John F. Schabron

Publication number: 20190299180Abstract: At least one embodiment of the inventive technology may involve the intentional changing of the stability of an emulsion from a first stability to a more desired, second stability upon the addition of a more aromatic asphaltene subfraction (perhaps even a most aromatic asphaltene subfraction), or a less aromatic asphaltene subfraction (perhaps even a least aromatic asphaltene subfraction) to a emulsion hydrocarbon of an oil emulsion, thereby increasing emulsion stability or decreasing emulsion stability, respectively. Precipitation and redissolution or sorbent-based techniques may be used to isolate a selected an asphaltene subfraction before its addition to an emulsion hydrocarbon when that hydrocarbon is part of an emulsion or an ingredient of a yet-to-be-formed emulsion.Type: ApplicationFiled: November 22, 2016Publication date: October 3, 2019Inventors: John F.

Patent number: 10221363Abstract: The inventive technology may involve, in particular embodiments, novel use of a non-porous, high surface energy stationary phase to adsorb, in reversible fashion, the most polar component of a resins fraction of an input hydrocarbon when a mobile phase is passed over the stationary phase. Such reversible adsorption prevents irreversibly adsorption of such components on active stationary phase(s) downflow of the non-porous, high surface energy stationary phase, thereby conserving stationary phase costs and increasing resolution of resins elutions, and accuracy of hydrocarbon component results. Aspects of the inventive technology may also involve a novel combination of a solubility based asphaltene component fractionating and analysis method and an adsorption chromatography method for separating and/or analyzing saturate, aromatics and resins components of an input hydrocarbon.Type: GrantFiled: May 27, 2016Date of Patent: March 5, 2019Assignee: The University of Wyoming Research CorporationInventors: John F. Schabron, Ryan B. Boysen, Eric W. Kalberer, Joseph F. Rovani, Jr.
