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

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

The present invention relates to a method for the fast formation of a gas hydrate. More specifically, the present invention relates to a method for the formation of a fed-batch-type gas hydrate, the method including a first step i) of injecting a fresh aqueous solution containing a potential feed hydrate into a reactor, a second step ii) of feeding gas into the reactor in which the fresh aqueous solution containing the potential feed hydrate is injected in the first step, so as to pressurize said gas, and a third step iii) of injecting a surfactant solution into the reactor in which the gas is pressurized in the second step, as well as to a method for the formation of a batch-type gas hydrate, in which the first step is switched in sequence with the third step.
