  • Apparatus and method for generation of control signal for Claus process optimization
    Patent number: 5176896
    Abstract: An apparatus and method for the generation of a control signal for the optimization of sulfur removal in a Claus process unit comprises oxidizing a portion of the tail gas stream exiting the Claus unit by contacting a portion of the tail gas with an oxygen-containing gas in the presence of a catalyst which oxidizes H.sub.2 S to SO.sub.2, measuring the temperature rise associated with the oxidation reaction, converting the measurement to an appropriate control signal, and using the signal to control the rate of air flow into the Claus unit.
