Any substantial spill offers a hazard to a much larger area than the immediate vicinity of the spill because the liquefied gas immediately vaporizes, forming a cloud that moves with ambient wind and mixes with the atmosphere. In order to assess the hazards of actual spills, says the author, and to develop strategies for probable spills, it would be desirable to have a mathematical model of the gas cloud. For a given geographical and meteorological condition, the model could provide data on gas cloud size, rate of growth, and gas concentration as a function of time and location. The gas cloud model would have two principal components: 1) a model of atmospheric dispersion and 2) a model of the interaction between the evaporating LNG spill and the ambient water. The latter model provides the evaporation rate of the LNG required as input data for the atmospheric dispersion model and is the subject of this paper.

  • Supplemental Notes:
    • An earlier paper on this subject (P-5411, Possibilities and Probabilities in Assessment of the Hazards of the Importation of Liquefied Natural Gas, by D.L. Jaquette, April 1975, 19 pp., $1.50) examines the whole range of what the author terms "accident scenarios" in an effort to estimate the actual risks in large scale importation operations. (See MRIS No. 18-126023).
