Consequence Analysis of LNG Leakage Accident Based on Numerical Simulation

Liquid Natural Gas (LNG) is a kind of quality and valuable industrial chemical, produced by compressing and cooling natural gas to -162 degree Celsius. The safety issues are worth concern, especially in the LNG storage and transportation processes (e.g. the ultra-low temperature may be threatening once leakage happens.) This article chooses the ISO 40-foot containers as demonstration for the flexible transportation way, which supports waterway, road, railway as well as multimodal transport. Due to the fact that relevant historical data is rare, a numerical simulation method used to simulate the LNG leakage accident, especially the consequence analysis of LNG leakage from tank containers. In order to increase the reliability of research, this article supposes two cases to do comparative analysis. The research findings would be helpful for the emergency planning and response of LNG accident.
