Abstract: PURPOSE: An apparatus and method for purifying exhaust gas from ships or offshore structures are provided to guarantee an installation space, and to effectively reduce NOx by a catalyst reaction. CONSTITUTION: An apparatus for purifying exhaust gas from ships or offshore structures includes an exhaust receiver(10), a SCR(Selective Catalytic Reduction) reactor(30), a bypass pipe(22), a control valve(24), and a heating unit. The exhaust receiver receives exhaust gas generated during engine combustion. The SCR reactor is placed at the rear end of a supercharger, and reduces NOx in the exhaust gas by a SCR catalyst reaction. The bypass pipe bypasses some exhaust gas without passing the gas through the supercharger. The temperature of the exhaust gas is compensated while the exhaust gas passes through the bypass pipe. The control valve is installed in the bypass pipe to adjust the amount of the exhaust gas passing through the bypass pipe. The heating unit increases the temperature of the exhaust gas before the gas flows into the SCR reactor. [Reference numerals] (AA) Waste heat
