The present invention relates to a gas treatment system and a ship having the same, wherein the gas treatment system may comprise: a liquefied gas storage tank which stores liquefied gas therein, and has a cargo pump for unloading liquefied gas, and a spray pump for cooling down by means of a spray nozzle; an evaporation gas compressor which compresses evaporation gas generated in the liquefied gas storage tank to supply the same to an engine; a forcible vaporization device which heats the liquefied gas discharged by the spray pump; a mist separator which performs gas-liquid separation with the liquefied gas heated in the forcible vaporization device; and a gas heater which heats the gas-phase liquefied gas separated in the mist separator to deliver the same to the flow of evaporation gas between the evaporation gas compressor and the engine. The spray pump pumps the liquefied gas at a pressure lower than the required pressure of the engine. The present invention is characterized by further comprising a boost pump, which is disposed between the spray pump and the forcible vaporization device to pressurize the liquefied gas by the required pressure of the engine. Therefore, excellent stability and reliability can be guaranteed. 본 발명은 가스 처리 시스템 및 이를 포함하는 선박에 관한 것으로서, 내부에 액화가스를 저장하며, 액화가스 하역용 카고 펌프와, 스프레이 노즐을 통한 쿨다운용 스프레이 펌프가 마련되는 액화가스 저장탱크; 상기 액화가스 저장탱크에서 발생하는 증발가스를 압축하여 엔진에 공급하는 증발가스 압축기; 상기 스프레이 펌프로부터 배출되는 액화가스를 가열하는 강제기화기; 상기 강제기화기에서 가열된 액화가스를 기액분리하는 미스트 세퍼레이터; 및 상기 미스트 세퍼레이터에서 분리된 기상 액화가스를 가열하여, 상기 증발가스 압축기에서 상기 엔진 사이의 증발가스 흐름에 전달하는 가스히터를 포함하며, 상기 스프레이 펌프는, 상기 엔진의 요구압력보다 낮은 압력으로 액화가스를 펌핑하며, 상기 스프레이 펌프와 상기 강제기화기 사이에 마련되어 상기 엔진의 요구압력으로 액화가스를 가압하는 부스트 펌프를 더 포함하는 것을 특징으로 한다.
