Large Leak Oil Tank Farm Fire And Accident Environmental Risk Evaluation Applied Research

With the rapid development of the national economy, the need for petrulem products increase dramatically ,oil depot capacity and oil tank are developing into large-scale. At present the constructing or plan to construct oil depots, especialy nantional reserve oil tanks, the volume of tank is about 100×104m3, some even reach it's volume of 2 000×104m3. Now the existance maxinal oil tank is 1000000m3. Due to the characteristics of inflammability, explosion hazard, corrosion and toxicity of petroleum products, there are potential risks in their storage and transportation. As for large petroleum facility, accidental disclosure and fire will lead to serious consequences, maybe disaster. Therefore, it is necessary to carry out potential environmental risk assessment on large-scale tank farm and probe into the uncertainty of risk assessment.Based on environment assessment theory, it analysisted the cause and dangerousness of large-size oil storege tank of happening leakage, fire and explosion accidents. Applied Faut Tree Analysis theory and DOW Chemistry Risk Assessment method to analysis fire and explosion dangerous. Give the cause of happening leakage, fire and explosion accidents .it is a reference to make the precautions of anti-fire & explosion accidents. As ChangXinDian oil depot for example, the correspond accident aftereffect is accouted , and estimted the risk and influense for environment , bring out some advice of large-size oil depot in risk assessment and safety management.
