Japanese Patent JP6681815
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a methane gas recovery system which can execute a step of preferable gasifying a subterranean methane hydrate with the heat treatment method and the Huff&PUFF method and then liquidizing efficiently the gasified methane gas for the purpose of storage and transportation while it has a comparatively simple structure.SOLUTION: The system is provided with a first heat medium flow channel L4, in which a first heat medium having heat of a hot water produced by a heat source 30 is conducted to a heater 11, a second heat medium flow channel C, in which a second heat medium which passes through at least one of a cooler 12 and a radiator 22 is conducted into a methane hydrate layer LA 2, and a methane gas flow channel L, in which a portion of gasified methane separated from methane hydrate of methane hydrate layer LA 2 is conducted to a heat source 30 as a fuel and the remainder portion of gasified methane is conducted to a heat absorber 21 and liquefied.SELECTED DRAWING: Figure 1
