Pollutants Emission And Dispersion From Elevated Gas Flare: C.S. Of Aghajary

Abstract

 The purpose of this research is to study the emission and dispersion of hydrogen sulfide gas (H2 S) from elevated flare in Aghajary compression station. This flare is used only during shut-down or start-up. This flare has ignition system, when the feed gas discharged to the flare will be ignited by sparks. It is very likely that the ignition system does not work or ignition is delayed. In this situation H2 S may come down to the ground level and if it's concentration be greater than 8 ppm it can endanger human health and lead to death. Gaussian-based dispersion models are widely used to estimate local pollution levels. The accuracy of such models depends on stability classification schemes as well as plume rise equations. A general plume dispersion model for a point source emission, based on Gaussian plume dispersion equation, was developed. A mathematical model formulated in a computer program written in Pascal language was utilized in finding the ground level concentrations of H2 S emitted from the elevated flare and final results compare with PHAST software results.
