Abstract: The present invention provides an apparatus for molding gas hydrate pellets that includes: a pulverizer in which dehydrated gas hydrates are pulverized; a cooler having a rotating shaft provided therein, comprising a plurality of agitation blades installed along a height direction of the rotating shaft and configured to cool the gas hydrates to a predetermined temperature; a decompressor configured to decompress the cooled gas hydrates to a predetermined pressure; and a pellet molder configured to mold the decompressed gas hydrates to pellets.

Abstract: The present invention relates to an apparatus comprising a reactor body to which gas and water are supplied to create a gas hydrate; an upper cover which is engaged to an upper portion of the reactor body, a scraper mounted rotationally within the reactor body, and a motor for providing a driving force to the scraper. It is possible to remove gas hydrate particles attached to at least one of an inner surface of the reactor body and an inner surface of the upper cover, by a rotary driving of the scraper. According to the invention, it is possible to prevent a material hindering a heat transfer by attaching on a wall surface of the reactor, through a process of scraping out gas hydrate particles, when the scraper which is rotationally driven about a center axis of the reactor is close to the inner surface of the reactor.

Abstract: The present invention provides an apparatus for storing gas hydrate pellets that includes: a storage tank having an inlet formed at a top portion thereof for having gas hydrate pellets injected therein; a transfer part formed at a lower portion of the storage tank so as to transfer the injected gas hydrate pellets to an outside of the storage tank; a rotating shaft vertically formed in the storage tank; a plurality of division plates coupled to the rotating shaft to partition an internal space of the storage tank, each having a bottom portion thereof formed above a top portion of the transfer part; an extension plate coupled to a lower portion of each of the division plates in such a way that the extension plate is movable up and down; and a guide formed at an upper portion of the transfer part and configured to guide the extension plate so as to allow the extension plate to be revolved by rotation of the rotating shaft without an interruption with the transfer part.

Abstract: The present invention provides an apparatus for regasifying gas hydrate pellets that includes: a cylinder; a piston coupled to an inside of the cylinder and configured to reciprocate up and down; a pellet providing part coupled to an one side of the cylinder in such a way that supply of gas hydrate pellets to the cylinder is adjusted by having one end thereof opened and closed by reciprocation of the piston; a pressure adjusting space having one end thereof coupled to a lower portion of the cylinder; a door formed in the pressure adjusting space and configured to define the pressure adjusting space; a transfer part having one end thereof coupled to the other end of the pressure adjusting space and configured to transfer the gas hydrate pellets; and a regasification part coupled to the other end of the transfer part and having heating water therein to allow regasification of the transferred gas hydrate pellets.

Abstract: According to an embodiment of the present invention, a gas-liquid circulating type gas hydrate reactor, includes: a reactor body configured to be supplied with gas and water to generate a gas hydrate; and a bubble generator configured to be disposed around a lower portion of the reactor body, wherein the gas supplied from the lower portion of the reactor body is jetted into the reactor body through the bubble generator. The gas-liquid circulating type gas hydrate reactor in accordance with the present invention makes it possible to jet gas at a high speed by using the bubble generator disposed at the low portion of the reactor body so as to promote the reaction of water and gas which are accommodated in the reactor body while forming a water stream at the lower portion of the reactor body that enables a smooth agitation of the water and the gas.
