Disclosed are a device and a method for manufacturing a natural gas hydrate. Provided is the device for manufacturing a natural gas hydrate comprising: an ice slurry generation unit for preparing ice slurry having 13-20% of ice at normal pressure; a first pipe, having one end connected to the ice slurry generation unit for withdrawing the ice slurry from the ice slurry generation unit, and in which a high-pressure pump for increasing pressure on the ice slurry is interposed; a hydrate preparation reactor, which is connected to the other end of the first pipe so as to receive the pressurized ice slurry, and to which natural gas is supplied and mixed, for generating natural gas hydrate slurry; a second pipe, having one end connected to the hydrate preparation reactor, for withdrawing the natural gas hydrate slurry; and a dehydrating portion, which is connected to the other end of the second pipe, for dehydrating the natural gas hydrate slurry.

Device and method for manufacturing natural gas hydrate

Disclosed is a device for revaporizing natural gas. Provided is a device for revaporizing natural gas hydrate pellets, comprising: a pellet charging portion for charging pellets which is formed with an upper valve and a lower valve so as to divide space for adjusting pressure; a storing portion, which communicates with the lower portion of the pellet charging portion, for receiving pellets when the lower valve is opened; a transfer screw, one end of which couples to the lower portion of the storing portion, for transferring the pellets in the storing portion; and a dissolving reaction tub, which is coupled to the other end of the transfer screw, receives pellets from the lower portion of the dissolving reaction tub, and which accommodates heating water.

Device for revaporizing natural gas

Disclosed herein is an apparatus for continuously producing and pelletizing gas hydrates. The apparatus includes a gas supply unit, a water supply unit and a reactor. Gas and water are respectively supplied from the gas supply unit and the water supply unit into the reactor. The gas and water react with each other in the reactor. The reactor includes a dual cylinder unit which forms a gas hydrate in such a way as to squeeze a slurry of reaction water formed by the reaction between the gas and water. The dual cylinder unit includes an upper cylinder, a lower cylinder and a connection pipe which connects the upper cylinder to the lower cylinder. The connection pipe has passing holes through which the reaction water in the reactor flows into and out of the connection pipe.

Apparatus and method for continuously producing and pelletizing gas hydrates using dual cylinder

Disclosed herein is an apparatus and method for continuously producing and dehydrating gas hydrates. The apparatus includes a gas source, a water source, a reactor, a spinning wheel, and a centrifugal separator. The gas source and the water source are connected to the reactor. Gas and water are respectively supplied from the gas source and the water source into the reactor and react with each other in the reactor to form gas hydrate slurry. The spinning wheel and the centrifugal separator are provided in the reactor. The spinning wheel supplies the formed gas hydrate slurry to the centrifugal separator. The centrifugal separator dehydrates the gas hydrate slurry. Water removed from the gas hydrate slurry by the dehydration of the centrifugal separator is re-supplied into the reactor.
