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

A hydrate production apparatus according to the present invention comprises: a main body unit having a reaction space in which a hydrate is produced therein; an inlet pipe unit connected to one side of the main body unit so as to introduce, into the reaction space, a host material and a guest material for producing the hydrate; an outlet pipe unit connected to the other side of the main body unit so as to discharge the hydrate produced in the reaction space to the outside; and a pulverizing device unit provided inside the reaction space so as to increase a reaction area for producing the hydrate by pulverizing, into fine-sized particles, an object to be pulverized, which is at least one of the introduced host material and guest material.

Hydrate production apparatus and water treatment apparatus using same

The present invention provides a method for preparing gas hydrates by reacting a plurality of guest gases with water, wherein a first guest gas has a higher water solubility than that of a second guest gas, and the pressure of the gas hydrate formation condition of the second guest gas is lower than the pressure of the gas hydrate formation condition of the first guest gas. While the traditional gas hydrate production method, wherein a single guest gas is reacted with water, is unsatisfactory in terms of cost effectiveness and productivity, the present invention provides improved production yield of gas hydrates and enables an easy production of gas hydrates at lower pressure.

Method for producing gas hydrate by reacting plurality of guest gases and water

A method for treating water using a salt desorption process of gas hydrates according to the present invention includes: (a) introducing water containing impurities and a plurality of guest gases into a reactor; (b) forming gas hydrates by causing the water and the plurality of guest gases to react under a first condition; and (c) dissociating a gas hydrate of one guest gas from among the plurality of guest gases by changing the first condition to a second condition, wherein the first condition refers to temperature and pressure conditions under which all of the plurality of guest gases form gas hydrates and the second condition refers to temperature and pressure conditions under which the gas hydrate of the one guest gas from the mixed gas hydrates is dissociated.

An embedded measurement device that is capable of measuring the component and a composition of a multi-phase flow fluid flowing in a pipe. The embedded measurement device includes: a high-pressure pipe tube in which the multi-phase flow fluid flows; a Raman probe that is partially inserted inside the high-pressure pipe tube and has an optical lens; and a Raman peak analysis unit that is connected to another part of the Raman probe. The device for measuring the composition of the multi-phase flow fluid measures a Raman peak intensity value of the multi-phase flow fluid in the high-pressure pipe tube by using the Raman probe, thereby determining the composition of the fluid.

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

A double helix gas hydrate reactor is disclosed. The reactor includes an inlet port () into which water and gas are supplied, an outlet port () disposed opposite the inlet port, a hollow jacket () extending from the inlet port to the outlet port, a hollow outer helix () installed in the hollow jacket, and an inner helix () installed in the outer helix. The gas and water that are supplied into the inlet port react with each other to form gas hydrate in a channel defined between the inner helix and the hollow jacket.

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.

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.

A separation, purification and recovery method of SF, HFCs or PFCs is disclosed, which comprises a step for forming a gas hydrate including components in addition to SF, HFCs or PFCs. It is possible to separate and recover fluoro-gas at a much lower cost as compared to a conventional method for thereby obtaining an economical effect and preventing an emission of SF, HFCs or PFCs which corresponds to Non-COhaving a higher earth warming index, which leads to preventing an earth warming phenomenon. So, the present invention might be widely applied.
