METHOD FOR RECOVERING GAS FROM GAS HYDRATE, RECOVERING APPARATUS AND METHOD FOR REGASIFICATION OF GAS HYDRATE

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for recovering a gas from a gas hydrate in high efficiency by supplying thermal energy to a geologic stratum containing a gas hydrate while preventing the thermal loss and heating the gas hydrate. SOLUTION: The method for the recovery of a gas from a gas hydrate present under the ground or under the sea bottom supplies thermal energy to the gas hydrate by driving a thermal energy radiation source placed near the position of the gas hydrate, decomposes the gas hydrate to generate a gas and recovers the generated gas through a special recovery pipe. The invention further provides an apparatus for carrying out the method and a regasificaiton method relating to the apparatus. COPYRIGHT: (C)2006,JPO&NCIPI
