Reed, R L

Excess heat generated in a thermal reaction zone of a Claus sulfur recovery plant is used, by means of a high boiling point heat transfer medium, to reheat the Claus plant process stream prior to high temperature Claus catalytic conversion, and/or to regenerate Claus catalyst on which sulfur is deposited, or for other functions. In another aspect, low temperature Claus catalytic converters are operated at equivalent pressures during a cycle comprising an adsorption phase, a regeneration phase, and a cooling phase.
