CNG储配站泄漏浓度安全性分析

Safety Analysis of Leakage Concentration in CNG Storage and Distribution Station

文章对某CNG储配站泄漏浓度进行安全性分析。通过调研周边环境,按照国家标准给出的安全距离,确定出居民楼有可能受天然气泄漏影响。运用Fluent软件对天然气泄漏和扩散浓度进行数值模拟,得出居民楼处的天然气浓度,再与相关标准进行对比,判断是否低于不伤害人体的浓度红线。经过模拟计算,结果为在浓度红线内,居民楼安全。

In this paper,the safety analysis of leakage concentration in a CNG storage and distribution station is carried out.By investigating the surrounding environment and the safety distance given by the national standard,it is determined that the residential building may be affected by the natural gas leakage.Fluent software is used to simulate the concentration of natural gas leakage and diffusion.The concentration of natural gas in residential building is obtained,and then compared with the relevant standards to determine whether it is lower than the red line that does not harm the human body.The simulation results show that the resident building is safe in the concentration red line.
