    Abstract: PROBLEM TO BE SOLVED: To provide the boil-off gas processing device and the liquefied gas tank for controlling incineration or disposal of the boil-off gas by reducing plant cost and operation cost required for the boil-off gas processing.SOLUTION: The boil-off gas processing device that reliquefies the boil-off gas 22 generated in the liquified gas tank 2 to store the liquified gas 21 and returns it in the liquified gas tank 2, include a boil off gas emission line 3 for emitting the boil-off gas 22 to the outside from the liquified gas tank 2, and the boil-off gas reliquefaction line 4 which immerses at least a part of the boil-off gas emission line 3 in the liquified gas 21 of the liquified gas tank 2. The boil-off gas reliquefaction line 4 has the pressure maintaining mechanism 42 to maintain the required pressure for the reliquefaction of the boil-off gas 22, and has a length L which can absorb the heat capacity having necessary for the reliquefaction of the boil-off-gas 22.
