PURPOSE: An apparatus and a method for ejecting boil-off gas are provided to improve the efficiency of recycled boil-off gas because the adsorption and desorption of the boil-off gas are effectively performed by having a jetting part, an adsorption and desorption device, a desorption part, a desorption heating part, and a cooling part. CONSTITUTION: An apparatus for ejecting boil-off gas comprises a first transferring pipe(4), a jetting part(100), a second transferring pipe(9), an adsorption and desorption device(10), and a third transferring pipe(14). The first transferring pipe is connected between a LNG storage part(1) and a LNG tank(2) of a ship. Boil-off gas generated in the LNG tank of the ship is transferred to the LNG storage part through the first transferring pipe. The jetting part comprises a transferring pipe(6), a jetting pump(7), and a jetting device(8). The transferring pipe is bypassed to the LNG storage part to transfer LNG in the LNG storage part. The jetting pump is arranged on the transferring pipe. The jetting device is installed in the end of the transferring pipe to jet the LNG. The second transferring pipe is connected to the LNG storage part to transfer the boil-off gas of which temperature is controlled. The adsorption and desorption device is connected to the end of the second transferring pipe and selectively adsorbs and desorbs the boil-off gas. The third transferring pipe transfers the boil-off gas desorbed in the adsorption and desorption device. |
