Abstract
A method for controlling a temperature of an incinerator may include determining a flow rate of a gas stream. The gas stream may be being passed from a sulfur recovery system to the incinerator. The method may include adjusting a target temperature of the incinerator. The target temperature of the incinerator is proportional to the flow rate of the gas stream. The method may include determining a temperature of the incinerator and adjusting the flow rate of a fuel gas being passed to the incinerator such that the temperature of the incinerator approaches the target temperature of the incinerator.
Claims19
A method for controlling a temperature of an incinerator, the method comprising:
- passing a gas stream comprising hydrogen sulfide from a sulfur recovery system to an incinerator;
- determining a flow rate of the gas stream;
- adjusting a target temperature of the incinerator, wherein the target temperature of the incinerator is proportional to the flow rate of the gas stream such that adjusting the target temperature of the incinerator comprises calculating the target temperature of the incinerator using an equation relating the flow rate of the gas stream to the target temperature of the incinerator;
- determining a temperature of the incinerator;
- passing a fuel gas to the incinerator;
- and
- adjusting the flow rate of the fuel gas such that the temperature of the incinerator approaches the target temperature of the incinerator.
A method for converting hydrogen sulfide to sulfur dioxide, the method comprising:
- passing a gas stream comprising hydrogen sulfide to an incinerator;
- passing an oxygen containing gas to the incinerator;
- passing a fuel gas to the incinerator;
- combusting at least a portion of the fuel gas to heat the incinerator;
- converting at least a portion of the hydrogen sulfide to sulfur dioxide in the incinerator;
- and
- passing a flue gas comprising sulfur dioxide from the incinerator, wherein the incinerator has a temperature controlled by:
- determining a flow rate of the gas stream;
- adjusting a target temperature of the incinerator, wherein the target temperature of the incinerator is proportional to the flow rate of the gas stream such that adjusting the target temperature of the incinerator comprises calculating the target temperature of the incinerator using an equation relating the flow rate of the gas stream to the target temperature of the incinerator;
- determining the temperature of the incinerator;
- and
- adjusting the flow rate of the fuel gas to the incinerator such that the temperature of the incinerator approaches the target temperature of the incinerator.
