Heat and mass transfer during the growth and dissociation of gas hydrates in porous media
An experimental technique for forming cores of propane hydrates converts a compacted zone of ice frost to hydrates by saturation with liquid propane at temperatures slightly above the ice point in order to study phenomena associated with the dissociation of hydrates in the earth. Current studies have found that the heat transfer coefficients between the hydrate and warm water vary from 100 to 4000 kcal/m/sup 2/-hr-/sup 0/C. Because these hydrates are a potential source of natural gas, understanding their formation and dissociation into gas and water in media similar to those existing in the earth is needed to develop models for gas production from naturally occurring hydrate zones that exist alone or in association with conventional gas reservoirs.
