(57) [Summary] [PROBLEMS] To reduce the water content by efficiently dehydrating a slurry-like natural gas hydrate, and reduce the cost of storage and transportation of the natural gas hydrate. SOLUTION: Centrifugal dehydration is performed while leaving many voids in the natural gas hydrate, and then the water contained in the natural gas hydrate that leaves many voids undergoes a hydration reaction with unhydrated natural gas. Dehydration by hydration is performed. |
