  • Method for analyzing total reactive sulfur
    Patent number: 5905195
    Abstract: The invention relates to a method for determining total reactive sulfur in a crude oil or fraction thereof using a mass spectrometer or gas chromatograph and mass spectrometer. Selecting fragment ions characteristic of reactive sulfur species enables the quantitative determination of total reactive sulfur species. The use of a low resolution mass spectrometer allows the rapid determination of total reactive sulfur in field or remote locations where more sophisticated instruments are not available.
    Type: Grant
    Filed: May 12, 1998
    Date of Patent: May 18, 1999
    Assignee: Exxon Research and Engineering Co.
    Inventors: Stilianos G. Roussis, James W. Fedora, Andrew S. Cameron
