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 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.
