The present invention relates to a gas treatment system and a ship including thereof, comprising: a storage tank storing liquefied gas; a propulsion engine using the liquefied petroleum gas as fuel; a fuel supply line supplying the liquefied gas of the storage tank to the propulsion engine; and a fuel collecting line which collects the remaining liquefied gas in liquid state discharged from the propulsion engine. The fuel supply line comprises a high-pressure pump, and a heat exchanger provided upstream of the high-pressure pump to change the temperature of the liquefied gas. The high-pressure pump receives the liquefied gas with a threshold pressure or less from the storage tank, while the heat exchanger controls the liquefied gas to be under the boiling point of the liquefied gas which is lower than a required temperature of the propulsion engine to prevent gas from being introduced into the high-pressure pump. In addition, a heater, which heats the liquefied gas to the required temperature of the propulsion engine, is disposed in the fuel supply line downstream from the high-pressure pump. Therefore, propulsion can be generated by using the liquefied petroleum gas.

    본 발명은 가스 처리 시스템 및 이를 포함하는 선박에 관한 것으로서, 액화가스를 저장하는 저장탱크; 액화석유가스를 연료로 사용하는 추진엔진; 상기 저장탱크의 액화가스를 상기 추진엔진에 공급하는 연료 공급라인; 및 상기 추진엔진에서 배출되는 잉여분의 액상 액화가스를 회수하는 연료 회수라인을 포함하며, 상기 연료 공급라인에는, 고압펌프와, 상기 고압펌프의 상류에 마련되어 액화가스의 온도를 변화시키는 열교환기가 마련되고, 상기 고압펌프는 상기 저장탱크로부터 임계압력 이하인 액화가스를 전달받고, 상기 열교환기는 상기 고압펌프로의 기체 유입 방지를 위해 액화가스를 상기 추진엔진의 요구온도보다 낮은 액화가스의 비등점 이하로 제어하며, 액화가스를 상기 추진엔진의 요구온도로 가열하는 히터가 상기 연료 공급라인에서 상기 고압펌프의 하류에 마련되는 것을 특징으로 하는 가스 처리 시스템을 갖는다.
