Disclosed is a device for reliquefying boil-off gas. According to the present invention, cold heat for reliquefying boil-off gas can be additionally supplied by using a compressor additionally installed for redundancy design, without the equipment of a high-capacity compressor. Accordingly, the reliquefaction capacity of the boil-off gas can be improved, even if the compressor with the same capacity is installed. The system for relieufying boil-off gas comprises: a first compressor for compressing a portion of the boil-off gas; a second compressor for compressing the other portion of the boil-off gas; a second expanding means for expanding a portion of flow; a heat exchanger for cooling the other portion of the flow; and a first expanding means for expanding a fluid.
증발가스 재액화를 위한 장치가 개시된다. 본 발명에 따르면 대용량의 압축기를 구비하지 않고도 리던던시 설계를 위해 추가적으로 구비된 압축기를 이용하여 증발가스 재액화를 위한 냉열을 추가적으로 공급할 수 있다. 따라서, 동일한 용량의 압축기를 구비하고도 증발가스의 재액화 용량이 향상된다.
