基于交叉模拟的苯储罐泄漏综合应急研究

Study on Comprehensive Emergency of Benzene Storage Tank Leaks Based on Cross-Simulation

苯泄漏引发的事故会对现场工作人员、设备和环境造成严重威胁,高效的应急工作会明显降低事故损失。当前石化企业安全、环保应急工作相对独立运行,存在安全、环保应急工作衔接不畅,应急效果不佳等问题。文章通过分析安全、环保应急侧重点,提出建立安全环保综合应急体系的建议,并基于环境风险评估软件BIA和安全后果分析软件PHAST交叉模拟分析,全面评估苯储罐泄漏导致毒性扩散、火灾、爆炸的影响程度和范围。据此设计安全环保综合应急救援程序,从而提高应急工作效率。

Accidents caused by benzene leaks result in a serious threat to on-site staff,equipment,and the environment.Efficient emergency response can significantly reduce the accident losses.Currently,the safety and environmental emergency response in petrochemical enterprises operate independently.And there are some problems such as a lack of well connection between safety and environmental emergency response efforts and poor emergency effect.In this article,through the analysis of the key aspects of safety and environmental emergency response,a propose on the establishment of the comprehensive safety and environmental emergency response system was put forward.Based on the cross-simulation analysis of the environmental risk assessment software BIA and the safety consequence analysis software PHAST,the impact extent and scope of the toxicity dispersion,fires,and explosions caused by benzene tank leakage were comprehensively assessed.Based on these results,a comprehensive emergency rescue procedure for safety and environmental was designed to improve the efficiency of emergency response efforts.
