Abstract: 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.

Abstract: 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.

Abstract: 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.
