Hydrate Dissociation in Sediment

摘要: An analytical model that describes hydrate dissociation under thermal stimulation in porous media is presented. The views the as a process which gas and water are produced at moving boundary. boundary separates dissociated zone containing from undissociated hydrate. A similarity solution to conservation equations derived, results presented graphical forms useful numerical computations. In particular, heat fluxes, temperature profiles, pressure distributions for two cases simulate saturated-steam hot-water stimulation. parametric study showed rate strong function of properties system porosity medium. energy efficiency process, defined ratio heating value relative input, was also computed. For stimulation, an about nine found, appears encouraging natural production
