Application of SAFETI in the Analysis of Natural Gas Pipeline Leakage Accident

摘要

Based on natural gas hazard properties analysis, this paper systematically summarized the types of the natural gas pipeline leakage accidents and analyzed the toxicity and flammable characteristics of natural gas pipeline leakage with the help of quantitative risk analysis Software DNV SAFETI(Software for Assessment of Flammable, Explosive and Toxic Impacts). According to the flammability analysis of natural gas, leakage can be caused by jet fire, fireball and explosion. Through the corresponding calculation model of SAFETI, risk degree of explosion and its consequences after formaldehyde leakage accident were calculated, which is truly useful to predict and to prevent natural gas pipeline leakage accident and to reduce individual risk and social risk respectively.
