LNG WATER VAPOUR EXPLOSION--ESTIMATE OF YIELDS AND PRESSURES

It has been suggested that many of the vapour explosion incidents involving LNG and water can be explained by the superheat theory which predicts an explosive work yield of 88 MJ per tonne LNG and an explosion pressure of 22 bars. However, there are some events that cannot be explained by this model and a calculational method to estimate the maximum possible yield has been described. This shows that, for situations where the LNG is the bulk liquid, a vapour explosion between LNG and water could yield 292 MJ per tonne LNG (402 MJ per tonne LNG if latent heat effects are included) with an explosion pressure of 46.5 bars. Similar calculations for an LPG/water system, with a water temperature at which explosions have been observed, give a yield of 117 MJ per tonne LPG with an explosion pressure of 40 bars.
