The present invention relates to a gas treatment system and a ship including the same, the gas treatment system comprising: a liquefied gas storage tank for storing liquefied gas; a pump for discharging the liquefied gas of the liquefied gas storage tank to the outside; a compressor for compressing boil-off gas generated from the liquefied gas storage tank and supplying the same to a consumer; a precooler provided upstream of the compressor and cooling the boil-off gas introduced into the compressor by spraying the liquefied gas supplied by the pump; a re-liquefaction device for re-liquefying surplus boil-off gas discharged from the liquefied gas storage tank and not consumed by the consumer into separate refrigerant; and a cooler provided between the compressor and the re-liquefaction device and cooling the boil-off gas introduced into the re-liquefaction device by spraying the liquefied gas supplied by the pump, wherein the amount of liquefied gas sprayed to the cooler is determined depending on the flow rate of boil-off gas transmitted from the compressor to the re-liquefaction device. Therefore, provided are a gas treatment system and a ship including the same, wherein stable re-liquefaction can be ensured.

    본 발명은 가스 처리 시스템 및 이를 포함하는 선박에 관한 것으로서, 액화가스를 저장하는 액화가스 저장탱크; 상기 액화가스 저장탱크의 액화가스를 외부로 배출하는 펌프; 상기 액화가스 저장탱크에서 발생하는 증발가스를 압축하여 수요처로 공급하는 압축기; 상기 압축기 상류에 마련되며 상기 펌프에 의해 공급되는 액화가스를 분사하여 상기 압축기로 유입되는 증발가스를 냉각하는 예냉기; 상기 액화가스 저장탱크에서 배출되고 상기 수요처에서 소비되지 않은 잉여분의 증발가스를 별도의 냉매로 재액화하는 재액화장치; 및 상기 압축기와 상기 재액화장치 사이에 마련되며 상기 펌프에 의해 공급되는 액화가스를 분사하여 상기 재액화장치로 유입되는 증발가스를 냉각하는 냉각기를 포함하며, 상기 냉각기에 분사되는 액화가스량은, 상기 압축기에서 상기 재액화장치로 전달되는 증발가스의 유량에 따라 결정된다.
