摘要
为探究高含硫天然气发生泄漏时危害影响因素的相互关系,基于火焰加速模拟器(FLACS)软件模拟,采用单因素分析和均匀设计法研究CH4和H2S体积分数含量比、通风速率和管道压力对高含硫天然气泄漏爆炸与毒性的影响。研究结果表明:影响高含硫天然气泄漏爆炸极限范围因素主次顺序为通风速率>管道压力>CH4与H2S含量比,其中通风速率负相关,管道压力、CH4与H2S含量比呈正相关,通风速率对爆炸极限范围影响最显著;影响泄漏毒性敏感主次因素相反,通风速率、含量比呈负相关,压力呈正相关,CH4与H2S含量比影响最显著。
In order to study interrelation between influencing factors in high-sulfur natural gas leakage accidents,single-factor analysis and uniform design method were used to study influence of CH4 and H2S content ratio,ventilation rate and pipeline pressure on explosion and toxicity risk of high-sulfur natural gas based on numerical simulation by FLACS software.The results show that factors influencing explosion limit of natural gas is ventilation rate>pipe pressure>CH4 and H2S content ratio,among which the first factor is negatively correlated with limit range while the other two are positively correlated with it,and ventilation rate has the most significant effect.It is the opposite for factors that affect gas leakage toxicity which is negatively correlated with ventilation rate and content ratio but positively correlated with pipeline pressure,and content ratio exerts the most significant effect on gas toxicity.
