The present invention relates to a liquefied gas treatment system, which includes: an evaporation gas compressor compressing an evaporation gas supplied from a liquefied gas storage tank; a first heat exchanger exchanging heat of the evaporation gas compressed by the evaporation gas compressor with an evaporation gas supplied from the liquefied gas storage tank; a pressure control part expanding or depressurizing the compressed evaporation gas first; a liquefying part expanding or depressurizing at least a part of the evaporation gas supplied from the pressure control part secondly; and a second heat exchanger which exchanges heat of the evaporation gas compressed by the evaporation gas compressor with the evaporation gas supplied from the pressure control part. The liquefied gas treatment system according to the present invention has the effect of improving operation efficiency of a reliquefaction system, since the heat exchangers re-liquefying the compressed evaporation gas are configured in parallel, and one heat exchanger re-liquefies the compressed evaporation gas using cold energy of the evaporation gas supplied from the liquefied gas storage tank and the other heat exchanger re-liquefies the evaporation gas using cold energy of the first-stage expanded or depressurized evaporation gas.

    본 발명은 액화가스 처리 시스템에 관한 것으로서, 액화가스 저장탱크에서 공급되는 증발가스를 압축하는 증발가스 압축기; 상기 증발가스 압축기에서 압축된 증발가스를 상기 액화가스 저장탱크에서 공급되는 증발가스와 열교환하는 제1 열교환기; 상기 압축된 증발가스를 1차 팽창 또는 감압시키는 압력조절부; 상기 압력조절부에서 공급되는 증발가스의 적어도 일부를 2차 팽창 또는 감압시키는 액화부; 및 상기 증발가스 압축기에서 압축된 증발가스를 상기 압력조절부에서 공급되는 증발가스와 열교환하는 제2 열교환기를 포함하는 것을 특징으로 한다. 본 발명에 따른 액화가스 처리 시스템은, 압축된 증발가스를 재액화하는 열교환기를 병렬로 구성하고, 하나는 액화가스 저장탱크에서 공급되는 증발가스의 냉열을 사용하여, 그 외는 1단 팽창 또는 감압된 증발가스의 냉열을 사용하여 재액화함으로써, 재액화 시스템의 운전 성능이 향상되는 효과가 있다.
