본 발명은 증발가스 재액화 시스템 및 선박에 관한 것으로서, 액화가스 저장탱크; 상기 액화가스 저장탱크에서 발생한 증발가스를 압축하는 압축기; 상기 압축기에서 압축된 증발가스를 냉각하는 증발가스 열교환기; 상기 증발가스 열교환기를 통해 냉각된 상기 증발가스를 감압하는 감압밸브; 및 상기 감압밸브를 통해 감압된 상기 증발가스에서 기체 상태의 플래시가스를 분리하는 기액분리기를 포함하며, 상기 증발가스 열교환기는, 복수 층의 기판 및 상기 기판의 측면에 마련되는 복수 개의 헤더를 포함하는 PCHE 타입이며, 상기 플래시가스 및 상기 액화가스 저장탱크에서 발생한 증발가스로 상기 압축기에서 압축된 증발가스를 냉각하는 것을 특징으로 한다.

    The present invention relates to a boil-off gas reliquefaction system, and a ship, comprising: a liquefied gas storage tank; a compressor compressing boil-off gas generated from the liquefied gas storage tank; a boil-off gas heat exchanger cooling the boil-off gas compressed from the compressor; a decompression valve decompressing the boil-off gas cooled through the boil-off gas heat exchanger; and a gas-liquid separator separating gaseous flash gas from the boil-off gas decompressed by the decompression valve. The boil-off gas heat exchanger is a PCHE type which has a plurality of headers arranged on multi-floor substrates and a lateral surface of the substrates. Moreover, the heat exchanger cools the boil-off gas compressed in the compressor using the flash gas and the boil-off gas generated from the liquefied gas storage tank.
