Title:
GREENHOUSE GAS EMISSION REDUCTION APPARATUS FOR VESSEL COMBINING EGR AND ICER, AND VESSEL INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2022/124464
Kind Code:
A1
Abstract:
Disclosed is a greenhouse gas emission reduction apparatus that is for a vessel and combines EGR and iCER. The apparatus comprises: an exhaust gas receiver (110) for removing pulsations by temporarily storing exhaust gas exhausted from each cylinder of a vessel engine (10); a supercharger (120) for supplying combustion air by compressing same using the exhaust gas supplied from the exhaust gas receiver (110); a cleaning part (130) for cleaning the exhaust gas that is supplied by passing through the supercharger (120), and then cooling the exhaust gas by circulating coolant, wherein the cleaning part (130) cleans the exhaust gas by spraying the exhaust gas with cleaning water to remove SOX and soot therefrom; a CO2 absorption part (140) for spraying an absorption solution onto, and thereby absorbing and removing CO2 from, the exhaust gas that has passed through the cleaning part (130); a combustion air receiver (150) which removes pulsations by temporarily storing the combustion air compressed by the supercharger (120), and charges the air into each of the cylinders of the vessel engine (10); and an exhaust gas circulation part (160) for supplying the supercharger (12) with the exhaust gas that has passed through the CO2 absorption part (140), and thereby mixing the exhaust gas with outside air. Therefore, by combining EGR and iCER, the present invention can reduce NOX generation, while preventing engine corrosion and improving combustion quality by absorbing CO2 and SOX and converting same into substances that do not have an effect on the environment, by means of EGR, and can increase engine efficiency and reduce methane slip by means of iCER.
