The present invention relates to a boil-off gas re-liquefaction system and a ship having the same, which can innovatively improve re-liquefaction performance by separating, cooling, and liquefying non-condensable gas. The system treating liquefied gas, a heavy hydrocarbon, includes: a compressor which compresses boil-off gas, in a multi-stage manner, generated from a liquified gas storage tank; a condenser which condenses the boil-off gas compressed from the compressor; a receiver which is provided at a lower part of the condenser and separates non-condensable gas; an intercooler which allows a part of liquid boil-off gas transmitted from the receiver and the remaining gas to mutually exchange heat, transmits vapor boil-off gas generated by the heat exchange to the compressor, and transmits liquid boil-off gas to the liquified gas storage tank; and a heat exchanger which cools the non-condensable gas separated from the receiver with at least a part of the liquid boil-off gas transmitted from the receiver.

    본 발명은 증발가스 재액화 시스템 및 이를 포함하는 선박에 관한 것으로서, 중탄화수소인 액화가스를 처리하는 시스템으로서, 액화가스 저장탱크에서 발생하는 증발가스를 다단으로 압축하는 압축기; 상기 압축기에서 압축된 증발가스를 응축시키는 응축기; 상기 응축기의 하류에 마련되며 불응축가스를 분리하는 리시버; 상기 리시버로부터 전달되는 액상 증발가스 중 일부와 나머지를 상호 열교환시키며, 열교환에 의해 발생한 기상 증발가스를 상기 압축기에 전달하고 액상 증발가스는 상기 액화가스 저장탱크로 전달하는 인터쿨러; 및 상기 리시버로부터 전달되는 액상 증발가스 중 적어도 일부로 상기 리시버로부터 분리된 불응축가스를 냉각하는 열교환기를 포함한다.
