EQUILIBRIUM CONDITION DECISION METHOD OF GAS HYDRATE BY FACET SURFACE OBSERVATION OF HYDRATE CRYSTAL, AND METHOD OF PRESERVATION AND TRANSPORTATION OF GAS HYDRATE USING THE SAME
PROBLEM TO BE SOLVED: To provide an equilibrium condition decision method of gas hydrate which decides an equilibrium temperature pressure condition of the gas hydrate at a high speed and with high accuracy, targeted to the gas hydrate in a state that three stable phases of hydrate-ice-gas are present, and to provide a method of preservation and transportation of the gas hydrate using the same.;SOLUTION: The equilibrium condition decision method of the gas hydrate and a method of preservation and transportation of the gas hydrate using the same are provided in which a change in facet surface shape of the gas hydrate crystal associated with temperature increasing operation is observed under a fixed pressure in a gas hydrate-ice-gas system, and the temperature just before the facet surface shape starts to change is used as an equilibrium temperature pressure condition of the gas hydrate.;COPYRIGHT: (C)2011,JPO&INPIT
