According to the present invention, a greenhouse gas emission reduction apparatus for a vessel is disclosed. The greenhouse gas emission reduction apparatus includes: a seawater supply part (110) supplying seawater; an absorption solution production part (120) producing and supplying a high-concentration CO2 absorption solution; an absorption tower (130) having a CO2 removal part (131) formed therein to remove CO2 by cooling exhaust gas discharged from a vessel engine (10) through a reaction between the exhaust gas and the seawater supplied from the seawater supply part (110), and converting CO2 into an ammonium salt solution through a reaction between the cooled exhaust gas and the absorption solution production part (120); and an absorption solution regeneration part comprising a first generation part (140) primarily regenerating the absorption solution through a reaction between the ammonium salt solution discharged from the abruption tower (130) and a bivalent metal hydroxide solution, and a second regeneration part (150) secondarily regenerating the high-concentration absorption solution through a reaction between a nonreacted ammonium salt solution from the primary regeneration end (140) and the bivalent metal hydroxide solution and circulating and supplying the absorption solution into the absorption tower (130) such that the ammonium salt solution can be reused as an absorption solution. Therefore, the present invention is capable of preventing a deterioration in absorption performance by increasing the recovery rate of the absorption solution and maintaining the same at a predetermined concentration.
본 발명은, 해수를 공급하는 해수 공급부(110), 고농도 CO2 흡수액을 제조하여 공급하는 흡수액 제조부(120), 선박 엔진(10)으로부터 배출되는 배기가스를 해수 공급부(110)로부터 공급된 해수와 반응시켜 냉각하고, 냉각된 배기가스와 흡수액 제조부(120)로부터의 흡수액을 반응시켜 CO2를 암모늄염 수용액으로 전환하여 CO2를 제거하는 CO2 제거부(131)가 형성된, 흡수타워(130), 흡수타워(130)로부터 배출된 암모늄염 수용액을 2가 금속수산화물 수용액과 반응시켜 흡수액을 1차로 재생하는 1차 재생부(140)와, 1차 재생부(140)로부터의 미반응 암모늄염 수용액에 2가 금속수산화물 수용액을 반응시켜 고농도 흡수액을 2차로 재생하고 흡수타워(130)로 순환 공급하여 흡수액으로 재사용하도록 하는 2차 재생부(150)로 이루어진, 흡수액 재생부를 포함하여, 흡수액의 회수율을 높여 일정 농도로 유지하여서 흡수성능 저하를 방지할 수 있는, 선박의 온실가스 배출 저감장치를 개시한다.
