Refinery flare stacks are designed to combust all manner of unrecoverable hydrocarbon gases and vapors to avoid putting them into the atmosphere in their original form. Steam is commonly added to the flare feed to assist mixing, ensure complete combustion of those hydrocarbons and avoid the formation of ugly plumes of black smoke. FIG. 1. Two steam flowmeters are required to achieve the needed turndown. The mixture of steam and hydrocarbon feed must be optimized since adding either too much or too little steam can reduce combustion efficiency and increase the emissions of volatile organic compounds (VOCs) that are supposed to be con
