The present invention provides an apparatus for reducing greenhouse gas emission in a vessel, comprising: an absorption tower including an absorption solution circulation supply unit that provides and circulates an absorption solution absorbing CO_2, an exhaust gas cooling unit cooling exhaust gas discharged from an engine of the vessel, and a CO_2 removal unit formed on the inner side of an engine casing and capturing CO_2 by reacting the cooled exhaust gas with the absorption solution to convert the CO_2 into a carbonate solution; an absorption solution regeneration unit that reacts a regeneration reactant of regeneration reactant storage tanks separately provided on the port side and the starboard side of the engine casing with a carbonate solution in a mixing tank to regenerate the absorption solution and generate a sediment; and a sediment treatment unit that separates the sediment and discharges the sediment overboard using seawater when discharging the sediment overboard, or stores the sediment in sediment storage tanks when storing the sediment onboard.
본 발명은, CO2를 흡수하는 흡수액을 제공하여 순환시키는 흡수액 순환공급부, 선박 엔진으로부터 배출되는 배기가스를 냉각하는 배기가스 냉각부, 엔진케이싱의 내측에 형성되고, 냉각된 배기가스와 흡수액을 반응시켜 CO2를 탄산염 수용액으로 전환하여 CO2를 포집하는 CO2 제거부를 포함하는, 흡수타워, 엔진케이싱의 포트측 및 스타보드측에 각각 분리되어 구비된 재생반응물 저장탱크의 재생반응물과 탄산염 수용액을 혼합탱크에서 반응시켜서, 흡수액을 재생하고, 침전물을 생성하는, 흡수액 재생부, 및 침전물을 분리하여, 선외배출시에는 해수에 의해 침전물을 선외배출하도록 하고, 선내저장시에는 침전물 저장탱크에 침전물을 저장하도록 하는, 침전물 처리부를 포함하는, 선박의 온실가스 배출 저감장치를 제공한다.
