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; and a fuel recovery unit which recovers a surplus of the liquid liquefied gas discharged from the propulsion engine and mixed with lubricating oil. 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, 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 compresses boil off gas and delivers the compressed boil off 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.
