A reliquefaction system is disclosed. The reliquefaction system according to an embodiment of the present invention comprises: a first supply line connected to a storage tank and provided with at least one compressor for receiving and compressing a fluid containing boil-off gas from the storage tank; a reliquefaction line connected to the rear end of the first supply line and supplying the fluid compressed through the compressor from the first supply line to a gas-liquid separator; and a first heat exchange unit connecting an upstream point of the compressor among the first supply lines and the reliquefaction line, and performing heat exchange between the fluid of the first supply line and the fluid of the reliquefaction line. An embodiment of the present invention is intended to provide the reliquefaction system in which a methane composition ratio of the gaseous fluid separated in the gas-liquid separator is high. 재액화시스템이 개시된다. 본 실시 예에 따른 재액화시스템은 저장탱크와 연결되며, 상기 저장탱크로부터 증발가스를 포함하는 유체를 공급받아 압축시키는 적어도 하나 이상의 압축기가 구비되는 제1 공급라인; 상기 제1 공급라인의 후단부에 연결되며, 상기 제1 공급라인으로부터 상기 압축기를 통해 압축된 유체를 상기 기액분리기로 공급하는 재액화라인; 및 상기 제1 공급라인 중 상기 압축기의 상류 지점과 상기 재액화라인을 연결하며, 상기 제1 공급라인의 유체와 상기 재액화라인의 유체 상호간에 열교환을 수행하는 제1 열교환부;를 포함하여 제공될 수 있다.
