Simulation and analysis of benzene leakage from sea transportation vessel based on PHAST
In order to prevent benzene leakage safety accidents in marine transportation,using PHAST software,with the benzene marine transportation ship as the research object,to explore the different leakage aperture size,wind speed on the benzene leakage after the diffusion distance and leakage caused by the pool fire,flash fire,jet fire and overpressure ex-plosion range of the influence of the law.The results show that after the accident,the diffusion distance of cloud leakage,the radius of radiation influence of jet fire and the radius of overpressure influence of explosion are directly proportional to the size of leakage aperture,and the diffusion distance of leakage and the radius of overpressure influence of explosion are in-versely proportional to the wind speed.Concentration of 100×106 and wind speed of 3 m/s,the leakage aperture size in-creased from 25 mm to 75 mm,the maximum distance of downwind diffusion expanded nearly 4 times,the maximum unilat-eral width of the cloud increased by 3 times.The smaller the wind speed,the more unfavorable to the benzene diffusion,making the safety distance farther,and the overpressure radius is larger,which results a higher risk.
