Abstract

Abstract: 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.

Key words: high-sulfur natural gas, simulation of flame acceleration simulator (FLACS), single factor analysis, uniform design method, correlation analysis
