Abstract
The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel cooperated with exhaust gas recirculation (EGR), and a vessel including the same, in which NOx generation is reduced, which is the original purpose of EGR, while maintaining existing EGR, SOx as well as CO2, which is the representative greenhouse gas, are absorbed and converted into materials that do not affect environments, and the materials are discharged or stored as useful materials, thereby preventing corrosion of an engine and improving combustion efficiency.
Claims17
An apparatus for reducing greenhouse gas emission in a vessel cooperated with EGR, the apparatus comprising:
- an exhaust gas receiver that temporarily stores exhaust gas exhausted from each cylinder of a vessel engine and removes pulsation;
- a cleaning unit that removes and cleans SOx and soot by spraying cleaning water to the exhaust gas supplied from the exhaust gas receiver and cools the exhaust gas by circulating cooling water;
- a CO2 absorbing unit that absorbs and removes CO2 by spraying an absorbent liquid to the exhaust gas having passed through the cleaning unit;
- and
- a scavenge air receiver that temporarily stores the exhaust gas having passed through the CO2 absorbing unit, removes pulsation, mixes the exhaust gas with scavenge air, and supplies the mixed gas to each cylinder of the vessel engine.
