Aboozar field offshore process is limited to oil / gas separation, and the produced gas from the separators is disposed in a common flare system in which more than standard cubic feet gas mixture are daily being flared. The flaring process can produce different pollutants such as SO as an index pollutant which has a substantial role in the environment and human health. This pollutant concentration depends on the gas composition sent to the flame and flare combustion efficiency. In highly polluted places, to monitor amount of each pollutant all over the region, we should always measure concentration of pollutant by pollutant emission modeling from the source not to need costly routinely measurement by some special devices.As the project target,we intend to model considered flare as a point source to investigate its concentration around the platforms to understand whether the concentration of pollutant is more than the standard limit value or not; and also to assess intensification impacts of flares pollutants. In this project, we have simulated SO emission by means of an intermediate model based upon the Gaussian model, and we tried to find out SO dispersion pathway after flame. This intermediate model that is often used before applying anadvanced air quality model so that determine if advanced modeling is needed. So, we predicted concentration of pollutant emitted by the flares in living quarters and production and wellhead platforms and specify hazardous zone where the most amount of SO is accumulated. Finally, an advanced model will be required if SO standard threshold limit value is not met.
