Abstract
Disclosed is a process for production of a gas hydrate, wherein the process comprises a gas hydrate production step, a cooling step, a depressurizing step and a re-cooling step. In the cooling step, the temperature (T) required for the cooling of the gas hydrate is adjusted to a temperature equal to or higher than a cooling limit temperature (t+t) (which is a sum of an equilibrium temperature (t) of the gas hydrate and a temperature for correction (t)) and equal to or lower than the freezing point (0° C.).
