The present invention relates to a gas treatment system and a vessel including the same. According to the present invention, the gas treatment system comprises: a low-pressure compression unit in which two steps of compressors for extremely low temperature, are provided in a row to compress boil-off gas of a liquefied gas storage tank; a high-pressure compression unit in which four or more steps of compressors for room temperature are provided to pressurize the boil-off gas pressurized by the compressors for extremely low temperature and supply the pressurized boil-off gas to a high-pressure consumer; a boil-off gas heat exchanger which makes a part of the boil-off gas, that is discharged from the high-pressure compression unit to be transferred to the high-pressure consumer, exchange heat with the boil-off gas introduced into the low-pressure compression unit; a pressure-reducing valve which reduces the pressure of the boil-off gas compressed in the high-pressure compression unit and then, having exchanged heat at the boil-off gas heat exchanger; and a liquefied gas gas-liquid separator which separates gas from liquid of the boil-off gas, of which pressure is reduced by the pressure-reducing valve, and transfers the liquid boil-off gas to the liquefied gas storage tank. The gas treatment system and the vessel including the same can efficiently supply gas to a consumer by meeting pressure demanded by the consumer.

    본 발명은 가스 처리 시스템 및 이를 포함하는 선박에 관한 것으로서, 가스 처리 시스템은 액화가스 저장탱크의 증발가스를 압축하는 2단의 극저온용 압축기가 병렬로 마련되는 저압 압축부; 상기 극저온용 압축기에서 가압된 증발가스를 가압하여 고압 수요처로 공급하는 4단 이상의 상온용 압축기가 마련되는 고압 압축부; 상기 고압 압축부에서 토출되어 상기 고압 수요처로 전달되는 증발가스 중 일부를 상기 저압 압축부로 유입되는 증발가스와 열교환하는 증발가스 열교환기; 상기 고압 압축부에서 압축된 후 상기 증발가스 열교환기에서 열교환된 증발가스를 감압하는 감압밸브; 및 상기 감압밸브에서 감압된 증발가스를 기액분리하여 액상 증발가스를 상기 액화가스 저장탱크로 전달하는 액화가스 기액분리기를 포함하는 것을 특징으로 한다.
