The present invention relates to a system and a method for evaporation gas re-liquefaction and, more particularly, to a system and a method for re-liquefaction for re-liquefying evaporation gas in a low-temperature liquefied gas carrier. The evaporation gas re-liquefaction system according to the present invention, which is a system for re-liquefying evaporation gas generated in a liquefied gas storage tank, includes: a first heat exchanger recovering cold heat of the evaporation gas generated in the liquefied gas storage tank; and a second heat exchanger; a multistage compression unit compressing the evaporation gas heated through at least one of the first and second heat exchangers; and an intermediate cooler supercooling the evaporation gas compressed by the multistage compression unit. The second heat exchanger may be provided in parallel to the first heat exchanger or may be provided in series at the front end or the rear end of the first heat exchanger.

    본 발명은 증발가스 재액화 시스템 및 방법에 관한 것으로, 더욱 구체적으로는, 저온 액화가스 운반선에서 증발가스를 재액화시키는 재액화 시스템 및 방법에 관한 것이다. 본 발명에 따른 증발가스 재액화 시스템은, 액화가스 저장탱크에서 발생하는 증발가스의 재액화 시스템에 있어서, 액화가스 저장탱크에서 발생한 증발가스의 냉열을 회수하는 제1 열교환기; 및 제2 열교환기; 상기 제1 열교환기 및 제2 열교환기 중 어느 하나 이상을 통과하여 가열된 증발가스를 압축하는 다단 압축부; 및 상기 다단 압축부에서 압축된 증발가스를 과냉각시키는 중간 냉각기;를 포함하고, 상기 제2 열교환기는 상기 제1 열교환기와 병렬로 마련되거나 상기 제1 열교환기의 전단 또는 후단에 직렬로 마련되는 것을 특징으로 한다.
