DME-LPG 혼합연료에 따른 사고결과 피해예측

DME(Dimethyl Ehther) is considered as an attractive fuel in terms of clean, environmentally friendly form of energy, multi-source and multi-purpose. As the physical properties of DME are almost similar to LPG, DME can be mixed with LPG and DME-LPG mixture fuels seem to be employed without major remodeling of the existing LPG supply infrastructure. However, little attention has been given to the effect of different DME-LPG mixture fuels on consequence analysis to adjacent facilities, buildings and etc. In this work, the consequence analysis by different DME-LPG mixture fuels has been done. The results were discussed in terms of release rate, jet fire, vapor cloud explosions, BLEVEs and etc. It was found that the consequences estimated from fire and explosion scenarios assumed were almost similar for both LPG and DME 20 %.
