Container for storing, transporting, and disassociating hydrate pellets and method for storing, transporting, and disassociating hydrate pellets by using same

摘要

Disclosed is a container for storing, transporting, and dissociating hydrate pellets, the container comprising: a first container (100) made up of a plurality of frames; a second container (200) which is rotatably installed inside the first container (100), stores hydrate pellets therein, and has an internal surface to which a heat insulating member is attached; and a refrigerating machine (300) which is installed inside the first container (100) and refrigerates the second container (200), wherein the second container (200) is equipped with a heating wire (210), which is heated to dissociate the hydrate pellets by being supplied with power, or with a hot water tube (220), through which hot water flows to dissociate the hydrate pellets, on the internal surface thereof.

1. A container for storing, transporting, and dissociating hydrate pellets, the container comprising:
a first container made up of a plurality of frames; a second container which is rotatably installed inside the first container, stores hydrate pellets therein, and has an internal surface to which a heat insulating member is attached; a refrigerating machine which is installed inside the first container and refrigerates the second container, a blade portion disposed on an external surface of the second container and connected to a rotating body, and a combining member which is detachably connected to the second container and prevents or allows opening of the second container, wherein the combining member includes: a first combining member of a cylinder shape which is connected to the second container and has a central hole, through which a Boiled Off Gas (BOG) nozzle extends, and a periphery portion in which a first gas nozzle and a first gas valve are embedded; a second combining member of a cylinder shape which is spaced apart from the first combining member by a predetermined distance and has a central hole, through which the BOG nozzle extends, and a periphery portion in which a second gas nozzle is embedded; and a thrust bearing which is installed between the first combining member and the second combining member and which combines the first and second combining members such that the second combining member is rotatable with respect to the first combining member, and wherein the blade portion rotates the second container by receiving rotational force of the rotating body, and wherein the second container is equipped with a heating wire, which is heated to dissociate the hydrate pellets by being supplied with power, or with a hot water tube, through which hot water flows to dissociate the hydrate pellets, on the internal surface thereof, and the second container is connected to the BOG nozzle to discharge BOG, generated in the second container, outside the second container, and wherein the BOG nozzle includes: a first BOG nozzle, which is connected to the second container and discharges the BOG in the second container outside the second container; a BOG valve connected to the first BOG nozzle and controls flow of the BOG through the first BOG nozzle; and a second BOG nozzle is connected to a BOG collecting apparatus and the BOG valve at respective ends thereof so that the BOG is discharged to the BOG collecting apparatus when the BOG valve is open, and wherein the second container is connected to a gas nozzle to discharge gas generated during dissociation of the hydrate pellets outside the second container, and wherein the gas nozzle includes: the first gas nozzle which is connected to the second container and which discharges the gas in the second container outside the second container; the gas valve which is connected to the first gas nozzle and controls flow of the gas through the first gas nozzle; and the second gas nozzle which is connected to the gas valve and a gas extracting apparatus at respective ends thereof and causes the gas to be extracted to the gas extracting apparatus when the gas valve is open.
