Abstract

The gas flare process is the most common process used to dispose of waste gas generated in oil and gas operations. However, waste gas incineration has been suggested as a better alternative to gas flaring. There have been no published studies completed to assess the emissions associated with waste gas incineration or a comparison to flaring. Thus, this study has attempted to determine the emissions of waste gas incineration, particularly during well testing operations of sour gas, and make a qualitative comparison to flaring. -- Thermodynamic properties combined with kinetic data were used to simulate a detailed model that examined the likely routes of formation of several toxic species during sour gas incineration. Reactions involving oxidation products, light hydrocarbons, complex sulphur species, aromatic hydrocarbons, and poly-aromatic hydrocarbons were studied. In addition, the effects of varying inlet oxygen, flow rate, and temperature on species formation in the combustion chamber and incinerator stack were also determined. A qualitative comparison was then performed on the simulated emission results and experimental measurements of emissions from a sour gas flare.
