PROBLEM TO BE SOLVED: To suppress the height of a cylinder of a dehydration column while maintaining the through-put of the dehydration column at the level of the through-put of the conventional dehydration column and to thereby reduce the construction cost, running cost, etc. SOLUTION: The gravity dehydrating type dehydrator is designed to introduce a gas hydrate (a) produced by reacting a gas (g) with water (w) together with the unreacted water into the dehydration column 5, lift the gas hydrate from the lower side of the dehydration column 5 to the upper side thereof and discharge the unreacted water from a filtration part 7 provided in the sidewall surface of the dehydration column 5 to the outside of the column during the lifting. The dehydration column 5 is a dehydration column 22 of a double cylindrical structure composed of two cylinders of an inner cylinder 23 and an outer cylinder 24. Filters 26a and 26b for dehydration are provided in both sidewall surfaces of the inner cylinder 23 and outer cylinder 24, respectively and the unreacted water is discharged from the two filters of the filter 26a provided in the inner cylinder and the filter 26b provided in the outer cylinder to the outside of the column.
