Description Flares are used in Alberta's oil and gas industry to safely treat H2S containing gas releases during emergencies, and gas well flow tests and as a means of disposing of gases that cannot be recovered economically. Despite the wide use of these flares, little data exists on the combustion efficiency of full-scale flares. Differential Absorption Light Detection and Ranging (DIAL) is a laser-based optical method that can remotely measure the concentration of hydrocarbons in the plume downwind of a flare. By combining DIAL measured 2D concentration maps with wind speed, the mass emissions of hydrocarbons in a flare plume can be calculated. The hydrocarbon combustion efficiency of the flare can then be determined by comparing hydrocarbon mass flux in the plume to that in the gas going to flare. During the spring of 2003, DIAL was used in Alberta to measure the combustion efficiency of one sour gas well test flare and two solution gas flares during normal operation. These flares covered tip exit velocities from 1 to 23 m/s and H2S concentrations in the flared gas from 0 to 11%. Measured combustion efficiencies based on hydrocarbons remaining in the plume ranged from 74 to 98%.
