선박에 설치된 액화천연가스 저장탱크에서 발생하는 증발가스를 재액화하기 위하여 증발가스를 냉각 유체로 사용하는 재액화 장치가 개시된다. 상기 선박용 증발가스 재액화 장치는, 상기 저장탱크로부터 배출되는 증발가스를 다단계로 압축시키는 다수개의 압축기; 상기 다수개의 압축기 후단에 각각 설치되어 증발가스의 온도를 낮추는 다수개의 냉각기; 상기 다수개의 압축기에 의해 압축된 증발가스와 상기 저장탱크로부터 배출되는 증발가스를 열교환시키는 자가열교환기; 상기 자가열교환기를 통과한 압축된 증발가스의 압력을 낮추는 감압장치; 상기 감압장치를 통과하며 재액화된 증발가스와 기체상태로 남아있는 증발가스를 분리하는 기액분리기; 및 상기 기액분리기 내부에 설치되어, 상기 기액분리기에 의해 분리된 기체상태의 증발가스에 액화천연가스를 분사하는 분사기;를 포함한다.

    Disclosed is an evaporation gas reliquefaction device using evaporation gas as a cooling fluid to re-liquefy the evaporation gas generated in a liquefied natural gas storage tank installed in a vessel. The evaporation gas reliquefaction device for a vessel includes: multiple compressors compressing the evaporation gas discharged from the storage tank at multi stages; multiple coolers lowering the temperature of the evaporation gas by being individually installed at a rear end of the multiple compressors; a self-heat exchanger heat-exchanging the evaporation discharged from the storage tank and the evaporation gas compressed by the multiple compressors; a decompression device lowering the pressure of the compressed evaporation gas passing through the self-heat exchanger; a liquid and gas separator separating the evaporation gas reliquefied by passing through the decompression device and the evaporation gas remaining in a gas state; and an injector installed in the liquid and gas separator and injecting liquefied natural gas to the evaporation gas of the gas state separated by the liquid and gas separator.
