Title:

METHOD OF MOLDING GAS HYDRATE PELLET

Document Type and Number:

WIPO Patent Application WO/2012/132980

Kind Code:

A1

Abstract:

[Problem] To provide a method of molding a gas hydrate pellet for conveniently handling a natural gas hydrate during a transporting or storing operation and thus improving the practical use of the natural gas hydrate. [Solution] When gas hydrate slurry supplied to a compression room (21) is pressurized and compressed by forwardly moving a compression plunger (21e), the moving speed of the compression plunger (21e) is lowered as much as possible, preferably kept lower than a displacement x 10-2 [m/min] where the displacement is a distance traveled by the compression plunger (21e) during compression. Owing to the low-speed movement, the bonding force between gas hydrate particles can be improved to be able to mold a gas hydrate pellet having large breaking strength.
