Formation of Dangerous Zones Due to Accidental Release of Liquefied Naturl Gas in Egypt
O. Badr and O. Al-Farouk
Abstract—The main objective of the present investigation is to study the environmental impact due to accidental spill of toxic and flammable liquefied natural gas (LNG) on land. Different case studies of possible accidents in Egypt were considered. US EPA-approved dispersion models were used to estimate the size and location of the formed dangerous zones at different elapsed times from the accident. The growth and decay of the dangerous zones for different concentration levels were also obtained showing them in downwind, crosswind, and vertical directions. In this study the toxicity of natural gas is measured by its concentration causing suffocation to humans while flammability is measure by its lowest concentration in air to cause fire in the presence of an ignition source. Two accidental scenarios of LNG spill from an instantaneous full rupture of a storage tank or a rupture of an external pipe connected to it have been considered. In both cases, constant area or constant thickness of the formed LNG pool were studied. Parametric studies were performed to investigate the effects of wind speed, atmospheric stability, and vertical height on the size of formed dangerous zones.
