Abstract

Abstract: Aiming at the actual situation of the buried sulfur natural gas pipeline leakage problem, with the finite volume method, the numerical simulation for volume fraction of hydrogen sulfide and methane of the buried sulfur natural gas pipeline continuous leakage were preceded. The upper soil was considered as porous medium to gas diffusion effects. Comparing and analyzing the dangerous area of methane and hydrogen sulfide occurring at the moment, the results show that the virulent area of hydrogen sulfide leaked is much greater than the dangerous area of methane, covering completely. Between the common area of hydrogen sulfide and methane, fire prevention measures are took as well as poisonous protection measures in the area of hydrogen sulfide influenced alone.

Key words: Hydrogen sulfide , Methane , Numerical simulation , Leak , Porous media

摘要： 针对埋地含硫天然气管道泄漏的实际情况,采用有限体积法,对埋地含硫天然气管道持续泄漏的甲
烷及硫化氢体积分数进行了数值模拟。在模拟过程中,考虑了管道上层土壤作为多孔介质对气体扩散的影响,比较
分析了同一时刻甲烷和硫化氢的危险区域,得出同一时刻硫化氢泄漏所造成的剧毒区域远大于且完全覆盖甲烷危
险区域。对硫化氢和甲烷的共同影响区域,应同时采取防火防毒措施,而在硫化氢影响区域只需采取防毒措施。
