VAPOR PRODUCTION FROM LNG SPILLS ON WATER
In a laboratory program by Shell Research Ltd., sponsored by the American Petroleum Institute, LNG evaporation rates were measured (1) on tanks of sea water supported on a load cell system, and (2) on a large pond. In (1), tests were performed to study the effect of LNG composition, amount of LNG per unit area, water temperature, and water agitation; in (2), LNG was pumped at a constant rate onto the water surface, and evaporation rates were obtained by observing the LNG pool area. Spreading continued until equilibrium was reached at about 0.16 lb of LNG per square foot of water. In the tank areas (9 and 40 sq ft), ice formation liberated latent heat, which increased the rate of evaporation; on the open pond, evaporation occurred without ice formation. Water picked up during evaporation increases the vapor density so that the plume tends to be wide and shallow. This work parallels an API program for large-scale LNG spills on water by Esso Research & Engineering Co.
