PROBLEM TO BE SOLVED: To provide a device for efficiently preparing hydrate slurry by preventing the supercooling of a water solution from being cancelled on a heating surface inside a heat exchanger. SOLUTION: The device for preparing the hydrate slurry as a mixture of the water solution and a hydrate by using a cooling medium for cooling the water solution of a guest compound which produces the hydrate at a temperature higher than 0°C comprises a first heat exchanger 2 for holding the water solution in a solved condition for supercooling and second heat exchangers 3a, 3b provided on the downstream side of the first heat exchanger 2 for cooling the hydrate slurry. It is acceptable to provide means for cancelling the supercooling of the water solution between the first heat exchanger 2 and the second heat exchangers 3a, 3b. COPYRIGHT: (C)2004,JPO |
