The present invention relates to a gas treatment system and a marine structure including the same. The gas treatment system includes: a boil-off gas supply line supplying boil-off gas produced from a liquefied gas storage tank to a gas combustion unit; a boil-off gas compressor provided on the boil-off gas supply line to compress the boil-off gas; a boil-off gas collection line branched from the downstream of the boil-off gas compressor to be connected to the liquefied gas storage tank, and including a boil-off gas heat exchanger and a gas-liquid separator cooling the boil-off gas; and a generation engine producing electricity by using the boil-off gas as a material. The generation engine produces more electric power than electric power required for the inside of a vessel if the flow rate of the boil-off gas supplied to the gas combustion unit through the boil-off gas supply line exceeds a preset flow rate. Therefore, the present invention is capable of increasing the rate of use of boiloff.

    본 발명은 액화가스를 처리하는 시스템 및 이를 포함하는 해양 구조물에 관한 것으로, 액화가스 저장탱크에서 발생하는 증발가스를 가스 연소 유닛에 공급하는 증발가스 공급라인; 상기 증발가스 공급라인 상에 마련되어 증발가스를 가압하는 증발가스 압축기; 상기 증발가스 압축기의 하류에서 분기하여 상기 액화가스 저장탱크에 연결되며, 증발가스를 냉각시키는 증발가스 열교환기 및 기액분리기를 구비하는 증발가스 회수라인; 및 증발가스를 원료로 이용하여 전기를 생산하는 발전엔진을 포함하고, 상기 발전엔진은, 상기 증발가스 공급라인을 통해 상기 가스 연소 유닛으로 공급되는 증발가스의 유량이 기설정된 유량을 초과하는 경우 선내 필요 전력보다 많은 양의 전력을 생산하는 것을 특징으로 한다.
