Patent number: 10746659Abstract: Systems and methods are provided for determining the organic silicon content of petroleum fractions, such as refinery fractions. This can be achieved in part based on performing solvent-enhanced selective filtration on a hydrocarbonaceous sample to substantially remove inorganic silicon from the sample while retaining at least a substantial portion of the organic silicon in the sample. After the solvent-enhanced selective filtration, the organic silicon content of the filtered sample can be determined. The ability to determine the organic silicon content of a sample can be used to identify crude fractions and/or refinery fractions that may cause contamination problems within a refinery while reducing or minimizing the occurrence of false positive tests that could result from detection of inorganic silicon.Type: GrantFiled: June 28, 2018Date of Patent: August 18, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Mustafa Al-Sabawi, Lindsay A. Mitchell

Patent number: 10738258Abstract: A method for improving fuel efficiency and energy efficiency, while maintaining or improving deposit control and cleanliness performance, in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil includes a base oil mixture. The base oil mixture includes a lubricating oil base stock as a major component, and at least one cobase stock, as a minor component. The at least one cobase stock is present in an amount sufficient to reduce kinematic viscosity (Kv100) of the base oil mixture as determined by ASTM D445, while maintaining or controlling cold cranking simulator viscosity (CCSV) of the lubricating oil as determined by ASTM D5293-15, such that the lubricating oil meets both kinematic viscosity (Kv100) and cold cranking simulator viscosity (CCSV) requirements for a SAE engine oil grade as determined by SAE J300 viscosity grade classification system.Type: GrantFiled: March 22, 2018Date of Patent: August 11, 2020Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Raymond G.

Patent number: 10703984Abstract: Systems and methods are provided for using an oxygen-containing gas as at least part of the stripping gas for the stripping zone or section in a fluidized coker.
