  • Control system for sulfur process
    Patent number: 4021201
    Abstract: The flow rate of the oxygen-containing gas to a process for the oxidation of the hydrogen sulfide in a sour gas to sulfur is regulated responsive to the lower of the sour gas pressure signal and a signal representing the value of the sour gas flow rate as modified by the ratio of hydrogen sulfide to sulfur dioxide in the gaseous reaction effluent, to maintain the desired ratio of hydrogen sulfide to oxygen fed to the process. The sour gas flow rate can be regulated responsive to the higher of the sour gas pressure signal and the oxygen-containing gas flow rate signal.
    Type: Grant
    Filed: July 1, 1976
    Date of Patent: May 3, 1977
    Assignee: Phillips Petroleum Company
    Inventors: Lucien H. Vautrain, Herbert A. Ems
