This paper takes the safety in emergency processes as the starting point, from the perspective of scenario deduction, to study the consequences of fire accidents for oil-gas storage and transportation. Through the statistical analysis of actual accident cases, 19 frequently occurring basic scenarios in emergency processes are summarized. The scenario evolution paths of fire accidents for oil-gas storage and transportation are given by analyzing the evolution law of the accident development. Fuzzy numbers are introduced to express experts' qualitative judgment on accident scenarios. The empirical probabilities of scenario nodes are obtained by defuzzification calculation, and the state probability of each scenario node is calculated by using the dynamic Bayesian network joint probability formula. Under the comprehensive consideration about the probability statistics of actual accident cases, the critical scenario nodes on the evolution path and their final scenario probabilities are jointly determined to realize the optimization of the scenario evolution path. By constructing the correlation between the optimized scenario evolution path and the accident consequences, an accident consequence prediction model is established. The occurrence probability of accident consequences is calculated by the defuzzification method and dynamic Bayesian network. The accuracy of the consequence prediction model is verified by the July 16 Dalian's Xingang Harbor oil pipeline explosion accident. The research results provide scientific basis for helping decision makers to make the effective emergency measures that are most conducive to the rapid elimination of accidents and reducing the severity of accident consequences. 相似文献

采用“厌氧消化-A/O-臭氧催化氧化-BAF”组合工艺对某农药企业污水处理站生化出水进行中试研究。中试装置设计处理规模为12 t/d,进水水质主要指标: COD为214~346 mg/L,ρ(NH3-N)为8~35 mg/L,TN为65~108 mg/L。经组合工艺处理后,出水COD为51.2~71.4 mg/L,ρ(NH3-N)为2.4~6.8 mg/L,TN为13.6~19.2 mg/L,出水水质可达到江苏省《化学工业主要水污染物排放标准》(DB 32/939-2006)中的一级标准。整套工艺对进水具有较强的耐冲击负荷能力,可适应难降解、高氮废水,具有较好的经济效益。 相似文献
