Patent number: 8455403Abstract: Use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of such particles is disclosed. One method is the application of post-polymerization process steps (and especially heat treatment) to advance the curing reaction and to thus obtain a more densely crosslinked polymer network. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles.Type: GrantFiled: December 29, 2011Date of Patent: June 4, 2013Assignee: Sun Drilling Products CorporationInventors: Jozef Bicerano, Robert L.

Patent number: 8450249Abstract: A method of introducing a drag reducing polymer into a pipeline such that the friction loss associated with the turbulent flow though the pipeline is reduced by suppressing the growth of turbulent eddies. The drag reducing polymer is introduced into a liquid hydrocarbon having an asphaltene content of at least 3 weight percent and an API gravity of less than about 26° to thereby produce a treated liquid hydrocarbon. The treated liquid hydrocarbon does not have a viscosity less than the viscosity of the liquid hydrocarbon prior to treatment with the drag reducing polymer. Additionally, the drag reducing polymer is added to the liquid hydrocarbon in the range from about 0.1 to about 500 ppmw.Type: GrantFiled: August 11, 2011Date of Patent: May 28, 2013Assignee: Phillips 66 CompanyInventors: Stuart N. Milligan, Ray L. Johnston, Timothy L. Burden, Wayne R. Dreher, Kenneth W. Smith, William F. Harris

Patent number: 8450250Abstract: A method of preparing a drag reducing polymer wherein the drag reducing polymer is able to be injected into a pipeline, such that the friction loss associated with the turbulent flow through the pipeline is reduced by suppressing the growth of turbulent eddies. The drag reducing polymer is injected into a pipeline of liquid hydrocarbon hydrocarbon having an asphaltene content of at least 3 weight percent and an API gravity of less than about 26° to thereby produce a treated liquid hydrocarbon wherein the viscosity of the treated liquid hydrocarbon is not less than the viscosity of the liquid hydrocarbon prior to treatment with the drag reducing polymer. The drag reducing polymer has a solubility parameter within 4 MPa1/2 of the solubility parameter of the liquid hydrocarbon. The drag reducing polymer is also added to the liquid hydrocarbon in the range from about 0.1 to about 500 ppmw.Type: GrantFiled: August 11, 2011Date of Patent: May 28, 2013Assignee: Phillips 66 CompanyInventors: Stuart N.

Patent number: 8450251Abstract: A system for reducing pressure drop associated with the turbulent flow of asphaltenic crude oil through a conduit. The crude oil has a high asphaltene content and/or a low API gravity. Such reduction in pressure drop is achieved by treating the asphaltenic crude oil with a high molecular weight drag reducing polymer that can have a solubility parameter within about 20 percent of the solubility parameter of the heavy crude oil. The drag reducing polymer can also comprise the residues of monomers having at least one heteroatom.Type: GrantFiled: August 11, 2011Date of Patent: May 28, 2013Assignee: Phillips 66 CompanyInventors: Stuart N.
