Abstract

The methane hydrate dissociation at an external pressure of 1 bar has been experimentally studied. The methane dissociation rate depends on the heat transfer intensity in the course of dissociation. Quasi-isothermal and nonisothermal conditions of clathrate dissociation have been compared. Under nonisothermal conditions, the dissociation rate depends on the heat flux density. The lowest heat flux was achieved in a quasi-stationary mode, and the highest heat flux was achieved through combustion of methane released from the clathrate powder. The 54-fold increase in heat flux leads to the ninefold increase in the methane dissociation rate. Depending on the heat flux density, the following variants of clathrate dissociation were observed: without self-preservation, partial self-preservation with one dissociation rate minimum, and partial self-preservation with two minima.
