Title:
PROCESS FOR PRODUCTION OF GAS HYDRATE
Document Type and Number:
WIPO Patent Application WO/2007/063915
Kind Code:
A1
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 (t1 + t2) (which is a sum of an equilibrium temperature
(t1) of the gas hydrate and a temperature for correction (t2))
and equal to or lower than the freezing point (0˚C).
