The present invention relates to a gas treatment system and a ship having the same. The gas treatment system comprises: a fuel storage unit which stores liquefied gas containing heavy hydrocarbon as a main component; a fuel supply unit which supplies the liquefied gas of the fuel storage unit to a propulsion engine of a ship in a liquid form; a fuel recovery unit which recovers a surplus of the liquid liquefied gas discharged from the propulsion engine and mixed with lubricating oil; and a re-liquefaction unit which re-liquefies boil-off gas generated in the fuel storage unit. The fuel storage unit comprises: a plurality of cargo tanks which store the liquefied gas as cargo; a fuel tank which stores the liquefied gas as fuel to be supplied to the propulsion engine, wherein the fuel tank comprises a high-pressure fuel tank which is an independent pressure vessel and stores the liquefied gas above the critical pressure, and a low-pressure fuel tank which is an independent pressure vessel and stores the liquefied gas below the critical pressure; and a fuel delivery unit which delivers liquefied gas from the low-pressure fuel tank to the high-pressure fuel tank. According to the present invention, the gas treatment system and the ship having the same can reduce environmental contamination and increase energy efficiency.

    본 발명은 가스 처리 시스템 및 이를 포함하는 선박에 관한 것으로서, 중탄화수소를 주성분으로 하는 액화가스를 저장하는 연료 저장부; 상기 연료 저장부의 액화가스를 선박의 추진엔진에 액상으로 공급하는 연료 공급부; 상기 추진엔진에서 배출되며 윤활유가 섞인 잉여분의 액상 액화가스를 회수하는 연료 회수부; 및 상기 연료 저장부에서 발생한 증발가스를 재액화하는 재액화부를 포함하며, 상기 연료 저장부는, 액화가스를 화물로 저장하는 복수 개의 카고탱크와, 액화가스를 상기 추진엔진에 공급할 연료로 저장하는 연료탱크를 포함하고, 상기 연료탱크는, 독립형 압력용기이며 액화가스를 임계압력 이상으로 저장하는 고압 연료탱크와, 독립형 압력용기이며 액화가스를 임계압력 미만으로 저장하는 저압 연료탱크를 가지며, 상기 저압 연료탱크에서 상기 고압 연료탱크로 액화가스를 전달하는 연료 전달부가 마련되는 것을 특징으로 한다.
