LNG SAFETY STUDY USING FLACS CFD-TOOL
At LNG facilities natural gas releases may take place, either as cryogenic spills, flashing or gaseous releases. Traditional methods to evaluate the consequences from such events are very simplified, estimating safety distances based on idealized spills and flat terrain assumptions. New 2D shallow water models have recently been implemented in the CFD model FLACS to better predict the pool spread during LNG spills. Effects of terrain and obstructions, ground thermal properties and more have been modeled, and the pool spread and vaporization models have been integrated into the FLACS 3D vapor dispersion and explosion model. For LNG stored at elevated temperature/pressure, new models to predict jet behavior during flashing releases are under development. FLACS has been successfully validated against the 33 tests in the Model Evaluation Protocol published by the Fire Protection Research Foundation of the NFPA. The new models have been applied to several LNG safety studies. One example study at an LNG receiving station in PRC optimizing the regasification facility layout will be presented in the paper. FLACS has been used to predict flammable gas cloud sizes and potential explosion overpressure loads at buildings resulting from various LNG and natural gas leaks at sea or on land. The results of the simulation study have had an impact on the design of the impoundment basin and on distances to administrative buildings, and have also been used to develop evacuation plans.
