APPARATUS FOR REDUCING GREENHOUSE GAS EMISSION IN VESSEL COOPERATED WITH EXHAUST GAS RECIRCULATION AND INTELLIGENT CONTROL BY EXHAUST RECYCLING AND VESSEL INCLUDING THE SAME

摘要

In the present invention, a supercharger 120 that compresses and supplies combustion air by the exhaust gas supplied from the exhaust gas receiver 110, and sprays cleaning water with the exhaust gas supplied through the supercharger 120 to SO _X and the chute. A cleaning unit 130 that removes and cleans, and circulates cooling water to cool the exhaust gas, and _{a CO 2} absorption unit 140 that absorbs and removes _{CO 2 by injecting an absorbent liquid into the exhaust gas that has passed through the cleaning unit 130} , by producing a high-concentration CO ₂ absorbing solution and the second a salt aqueous solution discharged from the absorbing liquid producing unit (150), CO ₂ absorbing unit 140 to be supplied to the CO ₂ absorbing section (140) reacts with the metal hydroxide aqueous solution of the absorbing solution and NH ₃ The exhaust gas circulation supplying the exhaust gas passing through the _{CO 2} absorbing unit 140 to the supercharger 120 and regenerating the _{absorbent liquid to be recycled and supplied to the CO 2} absorbing unit 140 to be reused as an absorbing liquid. Including the part 180, EGR and iCER are combined to reduce _{NO Xgeneration by EGR, while absorbing CO 2} and SO _X to convert to a material that does not affect the environment to prevent corrosion of the engine and improve combustion quality. A vessel equipped with a GHG emission reduction device combined with the ship's EGR and iCER, which improves the engine efficiency and reduces methane slip by iCER, recycles and reuses the absorbent, and prevents the decrease in the absorption performance of the absorbent.
