Abstract

The release of toxic chemicals is an important hazard of chemical plants. The purpose of this study is to compare Chemical Exposure Index (CEI) and a consequence modeling to determine the hazard distance of toxic chemical release, utilizing a gas refinery as the case study. The CEI was utilized and considerable release scenarios were determined. The PHAST model was performed for consequence modeling of the scenarios with highest airborne quantity. In the case of toxic chemical release based on both CEI and consequence modeling, the sludge catcher unit identified as the most dangerous unit. Hazard distances calculated by the CEI are significantly greater than consequence modeling. This is acceptable in terms of safety, but it may not be applicable in reality. The results of study showed a procedure for selecting an appropriate method in order to reduce costs and time.
