| Summary: | Nowadays, the release of hydrogen sulfide from storage capacity of oil and gas industries have become serious threat to lives and property near the leakage source. The storage capacity of natural gas containing hydrogen sulfide is large and widely distributed. Thus, an efficient, low cost tool needs to be available in order to analyze the dispersion. Computational Fluid Dynamic (CFD) Fluent has been proposed to study the emission of hydrogen sulfidein oil and gas industries especially from gas gathering station. This method contains four steps: firstly, set up a CFD model and monitor points, the data are taken from Malaysia Gas Gathering Station; secondly, solve CFD equations and predict the real-time concentration field of toxic gas releases and dispersions: thirdly calculate the toxic releases according to gas concentration by using modified Pasquill-Gifford (PG) approach. Lastly, analyze both results from CFD and modified PG approach. Comparison from both results will determine the efficiency of CFD tool for the study of toxic gas exposure. The result from this study can be used for further evaluation of counter-measure of hydrogen sulfide hazard in Malaysia Gas Gathering Station and to study the risk associated at the site. |
