Claim 0:
1. 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;
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; and
a turbo charger comprising:
a turbine that is rotated by high-temperature and high-pressure exhaust gas supplied from the exhaust gas receiver;
a compressor that is coupled to a rotation shaft of the turbine and rotated to compress the scavenge air and supply the compressed scavenge air to the scavenge air receiver;
an air suction filter that is formed on a suction port side of the compressor to filter foreign matter;
a scavenge air cooling module that cools the scavenge air supplied from the compressor to the scavenge air receiver;
a first control valve that controls a flow rate of the exhaust gas supplied from the exhaust gas receiver to the turbine; and
a second control valve that is formed in front of the first control valve to control a flow rate of the exhaust gas supplied to the cleaning unit.
