Patent number: 9695374Abstract: 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.Type: GrantFiled: August 7, 2013Date of Patent: July 4, 2017Assignee: Korea Institute Of Industrial TechnologyInventors: Ju Dong Lee, Kyeong Chan Kang, Joung Ha Kim, Jae Il Lim

Patent number: 9606063Abstract: 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.Type: GrantFiled: December 18, 2013Date of Patent: March 28, 2017Assignee: KOREA INSTITUTE OF INDUSTRIAL TECHNOLOGYInventors: Ju Dong Lee, Hyung Ho Jo, Young Cheol Lee, Joung Ha Kim, Hyoung Chan Kim, Kyung Chan Kang

Patent number: 8689813Abstract: A valve for preventing freeze-fracturing prevents accidental freeze-fracturing due to the freezing of water by draining water from a flow pipe before the danger of freezing occurs when the temperature of ambient air drops. The valve for preventing freeze-fracturing includes a housing coupled to a pipe port and a draining chamber provided in a portion of the housing that faces the pipe port. The draining chamber has therein a water inlet hole, which communicates with an inside of the flow pipe, and a water outlet hole, which communicates with an outside of the housing. A storage chamber is provided in a portion of the housing that is opposite the draining chamber, and contains therein a phase change material, which decreases in volume while changing in phase from liquid to solid.
