Predicted Impact of Spilled Liquefied Natural Gas from Nigeria Liquefied Natural Gas Plant on its Host Water Areas

F.A. Akeredolu, A.J. Isafiade and J.A. Sonibare

Abstract:
Spilled Liquefied Natural Gas (LNG) on water could be dangerous if not properly handled because of its cryogenic nature and this always necessitates quantification of dangers associated with such in marine transportation. Potential spills from Nigerian Liquefied Natural Gas (NLNG) plant located on the western coast of Bonny Island in Niger Delta area of Nigeria and their impacts on the host water were considered in this study. Simulations were carried out for different spill masses and vaporization rates established. In addition, radiation flux zone for a thermal flux of 5 kW m-2 (set limit for human tolerance) on the host environment was investigated. The percentage fatality of the host communities was established based on this limit. Simulated period for the smallest spill mass (70,000 kg) to vaporize is 128 sec. This mass could attain a maximum radius of 75 m with vaporization rate of 547 kg s-1. For the largest spill mass (14,500,000 kg, about a full tank load), simulated period of vaporization is 466 sec. with a maximum radius of 257 m and vaporization rate of 6,620 kg s-1. Bonny and Finima, the major towns around the Plant fall within the 5 kW m-2 allowable thermal flux for humans but the percentage fatality for this (in case of accident) on the host communities was predicted to be zero.
