Numerical study of LNG leakage and dispersion in loading area

Abstract

Abstract: Taking a LNG loading area as a model, according to the form and characteristics of LNG fire, FLACS software is used to simulate the hazards caused by tank car leakage in the LNG loading area. The scope of explosion damage is simulated and analyzed by steam cloud diffusion model, liquid pool fire model and steam cloud explosion model respectively. Through the establishment of diffusion model, the diffusion state and concentration, thermal radiation flux and explosion impact of LNG at different locations under environmental conditions are analyzed, providing reference for further optimizing LNG fire safety management and formulating fire emergency plans.

Key words: numerical simulation, liquified natural gas, liquid pool fire, steam cloud explosion, vapor cloud diffusion
