Abstract

The dissociation behavior of methane hydrate and the kinetics of gas hydrate formation at the interface between gas hydrate and fluid Were investigated experimentally and theoretically. As the behavior of dissociation of methane hydrate is an essential function of the commercial recovery of methane gas, the bulk-scale experiment on dissociation rate was conducted as functions of time, temperature and pressure. Based on the results, the replacement experiment of CO 2 and methane hydrate was performed to obtain fundamentals of the extraction of methane hydrate. The result suggests that the new concept for mining methane hydrate can be applied to the practical cases, such as marine sediments.
