某原油库设置事故应急池设计方案的探讨

Discussion on Building Emergency Pool in a Crude Oil Depot

鉴于过去石油库火灾爆炸事故造成对水体污染的教训和对应对措施的有关要求,以某大型油库为例,从罐区容积、防火堤设计、路边沟容量等方面,探讨了在库区设置事故缓冲池的设计方案。通过发生最不利事故时的液体量与防火堤内液体容纳能力的比对,给出了加高防火堤,不建液体收集池;建设液体收集池,适度加高防火堤;不加高防火堤而增容建设液体收集池3种方案,经过计算均可满足事故状态下油品泄漏的安全要求,因此方案合理可行,获得省安监局的认可。

According to the design requirements by the Provincial Safety Supervision Bureau of the corresponding measures for oil leakage in a crude oil depot,and the relevant regulations and rules to prevent the leakage of the accident liquid under the accident state,from volume of tank farm,design of fire dike,capacity of roadside trench,etc.,three solutions,i.e. construction,and non construction of accident liquid collecting pool,or construction of an accident liquid collecting pool in the surrounding area of the oil depot,were put forward respectively. All the three solutions for the oil depot were reasonable and feasible,which could solve the problem of collecting accident liquid under the accident condition,and were approved by the Provincial Safety Supervision Bureau.
