PROBLEM TO BE SOLVED: To provide a method for producing a mixed gas hydrate, in which a composition of a raw material mixed gas and a gas composition of a produced mixed gas hydrate can be provided as the same gas composition as quickly as possible. SOLUTION: This method for producing the mixed gas hydrate comprises a gas hydrate producing step of producing a gas hydrate slurry by reacting the mixed gas (g) with water (w), a dehydrating step of removing the water (w) from the gas hydrate slurry (s), a pellet molding step of producing a pellet from the gas hydrate after removing the water, a freezing step of freezing the gas hydrate pellet (p) by cooling it below the freezing point, and a decompression step of decompressing the frozen gas hydrate to a storing pressure. The mixed gas (g) supplied to the gas hydrate producing step is diluted using a gas m for dilution included as a main component of the mixed gas (g). COPYRIGHT: (C)2009,JPO&INPIT |
