The petroleum derived base oils comprises greater than 90 weight percent saturates and less than 300 ppm sulfur and is preferably selected from the group consisting of a Group II base oil, a Group III base oil, and mixtures thereof. These lubricant blends have surprising low Brookfield viscosities at ?40° C.Type: GrantFiled: December 2, 2004Date of Patent: August 11, 2009Assignee: Chevron U.S.A. Inc.Inventors: John M. Rosenbaum, Stephen J. Miller, Joseph M. Pudlak

Patent number: 7528097Abstract: A composition and method for a non-emulsion crude oil simulant containing biodegradable oil, and a terpene is disclosed and described. Biodegradable oils such as canola oil, cottonseed oil, and soybean oil can be particularly beneficial for use in connection with these oil simulants. Terpenes such as d-limonene can be included to provide oil simulant compositions which exhibit good oil simulant properties. Additives such as photochromic dyes, food dyes, food-grade antioxidants, microorganisms, and nutrients can also be used. These non-emulsion based oil simulants can be readily tailored and adjusted to approximate relevant properties of a specific target fluid for use in assessing oil spill response, containment, clean-up of equipment, percolation, and/or spill behavior.Type: GrantFiled: August 4, 2005Date of Patent: May 5, 2009Assignee: University of Utah Research FoundationInventors: Francis V. Hanson, John V. Fletcher, Alyssa M. Redding, Christopher Olson, Jumpol Jaturapitpornsakul

Publication number: 20090092712Abstract: The present invention relates to a sprayable oil composition comprising a blend of an oil, an edible solvent selected from the group consisting of triacetin, tripropionin, tributyrin, and ethyl acetate; and a preferably an emulsifier such as a lecithin. Advantageously, the viscosity of the blend can be controlled without interesterification of the solvent with the oil. Furthermore, such oil compositions can be effective sprayable oils such as for pan release applications while being substantially free of alcohols.Type: ApplicationFiled: October 4, 2007Publication date: April 9, 2009Inventors: Dilip K. Nakhasi, Roger L. Daniels
