  • Method of molding gas hydrate pellet
    Patent number: 9039949
    Abstract: 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.
