Sour gas is natural gas that contains measurable amounts of hydrogen sulphide (H2S). It is a colourless, flammable gas and is poisonous to humans and animals. Hydrogen sulfide at higher concentrations stops people and animals from breathing, so if it’s not handled properly, it can be deadly. H2S smells like rotten eggs and is heavier than air (tends to accumulate in low-lying areas. In the absence of concise and definite answers to the gas dispersion modelling, the difference between observations and perceptions compared to the numerical predictions could increase. These challenges and limitations needs to be addressed to make appropriate decisions in practical operations.
The PhD project aims to establish reliable predictive methods to overcome uncertainties in air dispersion modelling and consequence assessment of such toxic gas releases.
