摘要
Abstract
To further elucidate ethane pipelines'leakage and diffusion patterns and avoid the huge damage that leakage cause to the environment personnel around and properties,FLACS software was used to simulate ethane pipelines leakage and diffusion scenarios.Additionally,a full scale experiment on ethane leakage diffusion was conducted through three dimensional numerical calculations to verify the simulation results.The study shows that under a leakage aperture of 25mm,the leakage distance is farthest,and the resulting accident consequences are most severe.The impact of the radius of casualties caused by a leakis jet fire,vapor cloud explosion,and suffocation concentration in descending order.These research findings can provide a reference for studying factors influening ethane leakage diffusion consequencesand hazard range.关键词
