Abstract
In an embodiment, a method of controlling flaring of a combustion gas including a flare gas, a supplemental fuel gas, and an assist gas is provided. Models estimating, based on flow rates and in-situ speed of sound measurements in the gases, net heating value of the combustion gas within a flare combustion zone, combustion efficiency of the combustion gas, and smoke yield of the combustion gas are maintained. The method also includes receiving measurements of the gas flow rates and determining set points for flow rates of the fuel gas and/or the assist gas based upon the models that achieve a target combustion efficiency. When a difference between a determined set point and its corresponding flow rate for the fuel gas and/or the assist gas is greater than a corresponding predetermined tolerance amount, that flow rate can be adjusted to reduce the determined difference below the predetermined tolerance amount.
