A method is for molding a gas hydrate pellet for improving convenience of handling of a natural gas hydrate during transportation and storage, and thereby improving the practical use of the natural gas hydrate. Gas hydrate slurry is fed in a compression chamber, and pressure and compression are applied to the gas hydrate slurry by advancing a compression plunger. At that time, a stroking speed of the compression plunger is set minimum, preferably less than a value expressed by a stroke length of the compression plunger at compression×10−2 (m/min. By advancing the compression plunger at low speed, binding between particles of the gas hydrate is tightened, thereby the gas hydrate pellet with increased shearing strength can be molded.
A method of molding a gas hydrate pellet in a gas hydrate formation plant including a generator in which a raw material gas and water are fed and adapted for reacting the raw material gas with water under high pressure in the generator to produce a gas hydrate slurry and removing water from the gas hydrate slurry that is produced to mold the gas hydrate shiny into a gas hydrate pellet of desired size, the method, comprising:
