The present invention relates to a gas treatment system and a vessel comprising the same. The gas treatment system comprises: a low-pressure compression unit in which two steps of compressors for extremely low temperatures are provided in parallel to compress vapor gas of a liquefied gas storage tank; a high-pressure compression unit in which four or more steps of compressors for room temperatures are provided to pressurize the vapor gas pressurized by the compressors for extremely low temperatures and supply the same to a high-pressure consumer; a precooler provided between the liquefied gas storage tank and the low-pressure compression unit to receive liquefied gas from the liquefied gas storage tank and precool the vapor gas of the liquefied gas storage tank; a gas-liquid separator for vapor gas, which receives the vapor gas cooled by the precooler, separates gas from liquid, and transfers the gas to the low-pressure compression unit; and an over-pressure valve provided between the low-pressure compression unit and the high-pressure compression unit, and, when the vapor gas pressure on a rear end of the low-pressure compression unit is a certain pressure or higher, adding the vapor gas discharged from the low-pressure compression unit to the vapor gas supplied into the low-pressure compression unit. The gas treatment system and the vessel comprising the same can efficiently supply gas to consumers.

    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 액화가스 저장탱크와 상기 저압 압축부 사이에 마련되고, 상기 액화가스 저장탱크의 액화가스를 전달 받아 상기 액화가스 저장탱크의 증발가스를 예냉하는 예냉기; 상기 예냉기에서 냉각된 증발가스를 공급 받아 기상을 분리하여 상기 저압 압축부로 전달하는 증발가스 기액분리기; 및 상기 저압 압축부와 상기 고압 압축부 사이에 마련되고, 상기 저압 압축부 후단의 증발가스 압력이 일정 압력 이상이면 상기 저압 압축부에서 토출된 증발가스를 상기 저압 압축부에 공급되는 증발가스에 합류시키는 과압 밸브를 포함하는 것을 특징으로 한다.
