SAFETY DISTANCE ANALYSIS FOR DME FILLING STATION USING MODIFIED-INDIVIDUAL RISK
In the gas station, the failures of facility lead to accident which poses a significant threat to people and property. Recently Dimethyl Ether (DME) is considered as one of the most promising candidates for a substitute for LPG and Diesel fuel. Its physical properties are similar to explosive material (LPG, Diesel). So prior to commercialization, DMEs safety standards will be developed based on logical basement.In this paper we focused on safety distance of DME filling station. Hypothetical DME filling station was modeled based on DME-LPG mixed filling station designed by KOGAS. And safety distance was suggested with quantitative risk constraint.We suggest the quantitative risk assessment approach through individual risk calculation. Individual risk calculation was performed with consequence analysis and failure mode under varying accident scenarios. Subsequently, the outcome shows that individual risk has each risk contour to suggest safety distance.According to the above-mentioned quantitative risk estimation result, we propose separation distance based on accident scenarios for each facility. The result of separation distance will be useful to determine facility layout and safety management of filling station.
