Patent number: 10179884Abstract: Disclosed are a device and a method for manufacturing a natural gas hydrate. Provided is the device for manufacturing a natural gas hydrate comprising: an ice slurry generation unit for preparing ice slurry having 13-20% of ice at normal pressure; a first pipe, having one end connected to the ice slurry generation unit for withdrawing the ice slurry from the ice slurry generation unit, and in which a high-pressure pump for increasing pressure on the ice slurry is interposed; a hydrate preparation reactor, which is connected to the other end of the first pipe so as to receive the pressurized ice slurry, and to which natural gas is supplied and mixed, for generating natural gas hydrate slurry; a second pipe, having one end connected to the hydrate preparation reactor, for withdrawing the natural gas hydrate slurry; and a dehydrating portion, which is connected to the other end of the second pipe, for dehydrating the natural gas hydrate slurry.Type: GrantFiled: January 15, 2016Date of Patent: January 15, 2019Assignees: Daewoo Engineering & Construction Co., Ltd., Samsung Heavy Ind. Co., Ltd., Sung-Il Turbine Co., Ltd., Dongguk University Industry-Academic Cooperation FoundationInventors: Myung Ho Song, Yong Seok Yoon, Hye Jung Hong, Jung Huyk Ahn, Mun Keun Ha, Seok Ku Jeon, Hoon Ahn, Ta Kwan Woo

Patent number: 9308507Abstract: Disclosed is a device for revaporizing natural gas. Provided is a device for revaporizing natural gas hydrate pellets, comprising: a pellet charging portion for charging pellets which is formed with an upper valve and a lower valve so as to divide space for adjusting pressure; a storing portion, which communicates with the lower portion of the pellet charging portion, for receiving pellets when the lower valve is opened; a transfer screw, one end of which couples to the lower portion of the storing portion, for transferring the pellets in the storing portion; and a dissolving reaction tub, which is coupled to the other end of the transfer screw, receives pellets from the lower portion of the dissolving reaction tub, and which accommodates heating water.Type: GrantFiled: August 23, 2010Date of Patent: April 12, 2016Assignees: Dongguk University Industry-Academic Cooperation Foundation, Samsung Heavy Ind.
