考虑安防措施的撬装氢压缩机系统安全性分析
Safety Study of a Skid Mounted Hydrogen Compressor Considering Protection Measures
摘要
Abstract
This paper summarizes and analyzes the hydrogen safety accidents of hydrogen compressors based on the description of skid-mounted compressor systems;then,a fault-tree-based hazard identification of skid-mounted hydrogen compressor systems is carried out for combustion and explosion accidents caused by hydrogen leakage;after that,an event tree analysis is applied to study the consequences and probability of hydrogen safety accidents considering system protection measures;finally,the consequences of jet flame,flash fire and explosion accidents caused by the hydrogen leakage considering protection measures is carried out based on FLACS software,combined with personal and building injury standards;besides,the optimization suggestions of safety equipment are proposed.The study shows that hydrogen leakage is mainly triggered by design faults and operational errors.Besides,failure of protection measures has a greater impact on fire or explosion events caused by hydrogen leakage;the probabilities of hydrogen safety accidents are all less than 3.3×10-3/year,and jet fire happens the most frequently.In addition,the results of the accidents consequences show that,for the jet fire,the max temperature is 2329.8℃,and the maximum heat flux density is 399.0kW/m2;for the flash fire accident,the maximum damage radius is 7.7m,the highest temperature is 3069.5℃;for the explosion accident,the maximum damage radius is 5.5m,the maximum overpressure of 10 bar.These accidents will cause serious personal injury and container structure damage.In addition,the safe distance should be larger than 7.7m.Moreover,the safety of the system can be effectively enhanced by improving the sensitivity of the hydrogen concentration sensor,optimizing the layout position of the hydrogen concentration sensor and enhancing the exhaust air volume of the exhaust system.关键词
