  • Methods and apparatuses for spectral qualification of fuel properties
    Patent number: 10295521
    Abstract: A method for determining property values of fuels may include using spectral data collected from one or more other fuels or fuel components. The method may include construction of spectral data representative of a fuel by weighting spectral data for another fuel and spectral data for one or more fuel components.
    Type: Grant
    Filed: June 16, 2017
    Date of Patent: May 21, 2019
    Assignee: TESORO REFINING & MARKETING LLC
