含硫天然气管道破裂硫化氢扩散的影响分析

ANALYSIS ON THE INFLUENCE OF DIFFUSED SULFURETED HYDROGEN FROM BROKEN SOUR NATURAL GAS PIPELINE

气体扩散过程十分复杂,受诸多因素的影响。同时,含硫天然气的运输存在一定的安全风险,因此,研究含硫天然气管道破裂后硫化氢扩散的影响范围具有重要的意义。通过对不同长度的含硫天然气管道泄漏后硫化氢扩散影响范围的分析,得出硫化氢含量,风速、破裂面积以及地形地貌对事故后果的影响规律,以期为含硫天然气管道的安全标准提供参考。

Gas diffusion process is very complex.It is influenced by many factors.Meanwhile,there are certain security risks in the transportation of sour gas.Therefore,it is of great significance to study the influence of diffused sulfureted hydrogen from broken sour natural gas pipeline.After analyzing the diffused sulfureted hydrogen from broken sour natural gas pipeline of different length,this paper found out the influence regularity of the content of sulfureted hydrogen,wind speed,rupture area and topography on the consequences of the accidents.And the authors hope to provide reference for the safety standards for sour natural gas pipeline.
