  • Method and system for measuring RON and MON values for light distillates
    Patent number: 8646312
    Abstract: A method and a system is disclosed for determining RON and/or MON values from constant volume combustion chamber apparatuses capable of producing pressure versus time combustion profiles having a fast combustion region and a slow combustion region, where data from the two regions is used to compute RON and/or MON values for light distillate fluid samples using a series expansion equation.
    Type: Grant
    Filed: December 3, 2007
    Date of Patent: February 11, 2014
    Assignee: Petroleum Analyzer Company, LP
    Inventors: G. Patrick Ritz, Didier Pigeon
