The present invention relates to a gas processing system and a ship including the same which increase the operating stability of an entire system. The gas processing system comprises: a liquefied gas storage tank; a boil-off gas compressor to compress boil-off gas of the liquefied gas storage tank in multiple stages to supply compressed boil-off gas to an engine; a forcible evaporator to forcibly evaporate liquefied gas of the liquefied gas storage tank to transfer evaporated gas to boil-off gas; and a reliquefaction device to liquefy surplus boil-off gas not consumed by the engine in the boil-off gas compressed by the boil-off gas compressor into a refrigerant. The boil-off gas compressor is provided in an oil-free centrifugal type to prevent lubricating oil from being mixed in the boil-off gas transferred to the reliquefaction device. The forcible evaporator transfers forcibly evaporated liquefied gas to boil-off gas upstream of the boil-off gas compressor. The boil-off gas compressor controls a discharge flow in response to a load change of the engine to adjust an engine-side supply amount of liquefied gas and boil-off gas.

    본 발명은 가스 처리 시스템 및 이를 포함하는 선박에 관한 것으로서, 액화가스 저장탱크; 상기 액화가스 저장탱크의 증발가스를 다단으로 압축하여 엔진으로 공급하는 증발가스 압축기; 상기 액화가스 저장탱크의 액화가스를 강제기화하여 증발가스에 전달하는 강제기화기; 및 상기 증발가스 압축기에 의해 압축된 증발가스 중 상기 엔진에서 소비하지 않는 잉여 증발가스를 냉매로 액화하는 재액화장치를 포함하고, 상기 증발가스 압축기는, 상기 재액화장치로 전달되는 증발가스에 윤활유가 혼입되지 않도록, 오일-프리(oil-free)인 원심형 타입(Centrifugal type)으로 마련되며, 상기 강제기화기는, 강제기화된 액화가스를 상기 증발가스 압축기 상류의 증발가스에 전달하며, 상기 증발가스 압축기는, 상기 엔진 로드의 변화에 대응하여 토출 유량을 제어하여 액화가스 및 증발가스의 엔진측 공급량을 조절하는 것을 특징으로 한다.
