According to an embodiment of the present invention, a gas treatment system comprises: a pump supplying liquefied gas stored in a liquefied gas storage tank to a propulsion engine; a boil-off gas compressor compressing boil-off gas generated in the liquefied gas storage tank; a heat exchanger heat exchanging the liquefied gas supplied from the pump with the boil-off gas supplied from the boil-off gas compressor; and a boil-off gas circulation line formed to enable the boil-off gas generated in the liquefied gas storage tank to return to the liquefied gas storage tank, and provided with the heat exchanger. At least a portion of the boil-off gas is re-liquefied in the heat exchanger to return to the liquefied gas storage tank by the boil-off gas circulation line without being heat exchanged by additional refrigerant.

    본 발명의 일 실시예에 따른 가스 처리 시스템은, 액화가스 저장탱크에 저장된 액화가스를 추진엔진으로 공급하는 펌프; 상기 액화가스 저장탱크에서 발생된 증발가스를 압축하는 증발가스 압축기; 상기 펌프로부터 공급되는 액화가스와 상기 증발가스 압축기로부터 공급되는 증발가스를 열교환하는 열교환기; 및 상기 액화가스 저장탱크에서 발생된 증발가스가 다시 상기 액화가스 저장탱크로 복귀하도록 형성되며 상기 열교환기를 구비하는 증발가스 순환라인을 포함하고, 상기 증발가스는, 상기 열교환기에서 적어도 일부가 재액화된 후 별도의 냉매에 의한 열교환없이 상기 증발가스 순환라인에 의해 상기 액화가스 저장탱크로 리턴되는 것을 특징으로 한다.
