  • Patent number: 8202353
    Abstract: A separation, purification and recovery method of SF6, HFCs or PFCs is disclosed, which comprises a step for forming a gas hydrate including components in addition to SF6, 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 SF6, HFCs or PFCs which corresponds to Non-CO2 having a higher earth warming index, which leads to preventing an earth warming phenomenon. So, the present invention might be widely applied.

  • Publication number: 20120082590
    Abstract: Disclosed is a gas hydrate reactor including a supply line for supplying water and gas, a thermoelectric module assembly, a front panel including an observation window, and a housing to which the thermoelectric module assembly and the front panel are attached and into which water and gas are supplied using the supply line so that a gas hydrate is formed therein. This reactor enables rapid and precise temperature control, thus allowing accurate data about properties to be easily acquired in kinetics, phase equilibrium, morphology and microscopic (Raman, XRD, etc.) research of a gas hydrate, thereby leading to the discovery of a gas hydrate production/decomposition mechanism and ensuring important information necessary for a gas hydrate application process.

  • Publication number: 20110263913
    Abstract: 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.

  • Publication number: 20110064643
    Abstract: 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.
