Example of Long Range Toxic H2S Gas Dispersion

IBEX Analytics specializes in Toxic, Flammable and Asphyxiating Gas Dispersion Analysis. Example shown here outlines our typical LONG RANGE dispersion modeling approach for a semi-heavy density gas (H2S) dispersing across a Mountain range. The same technical approach is applicable to Flammable and Asphyxiating gases such as CO2. The example oil production was characterized by its high H2S content. H2S is a hazardous gas which given a loss of containment scenario can disperse and potentially threaten the nearby population. The proposed plant site was surrounded on almost all sides by population centers of varying sizes and proximities. The objective of this study was to determine the possibility of H2S gas reaching these population centers following the occurrence of a worst-case loss of containment scenario. The project has defined the potential source of the worst-case loss of containment scenario as the planned Gas Injection unit located close to the proposed Central Production Facility (CPF).
