The apparatus for liquefying natural gas includes a gas compressor configured to receive and compress the natural gas from a natural gas feed stream, a heat exchanging unit configured to cool a high-pressure natural gas passing through the gas compressor through heat exchange, an expansion valve configured to expand the cooled natural gas passing through the heat exchanging unit, a hold-up drum configured to phase-separate a gas-liquid mixture produced by passing through the expansion valve and divide the gas-liquid mixture into a liquefied natural gas and a cryogenic recycle gas having nitrogen content greater than that of the liquefied natural gas so as to discharge the liquefied natural gas and the cryogenic recycle gas, and a bypass line configured to provide the recycle gas discharged from the hold-up drum to the heat exchanging unit.

Apparatus for liquefying natural gas and method for liquefying natural gas

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

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.

Method and apparatus for improving heat transfer and reaction efficiency of gas hydrate reactor using scraper

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.

Apparatus for storing gas hydrate pellets

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.

Apparatus for revaporizing gas hydrate pellets

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

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.

Gas-liquid circulating type of hydrate reactor

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.
