GRAVITY SPREADING AND ATMOSPHERIC DISPERSION OF LNG VAPOR CLOUDS

Present methods for estimating the extent and location of flammable vapors as a function of spill and weather conditions, assuming that ignition does not occur. Although various Gaussian dispersion models developed for describing the behavior of pollutants in the atmosphere are available, these models are for neutrally buoyant effluents and are only valid for describing LNG vapor dispersion at distance far enough downwind of the source so that details of the source behavior are unimportant.
