Abstract: The Marine environment protection committee has set a series of rules in order to prevent air pollution from ships. In the future, ships need to set up a SCR (Selective Catalytic Reduction) system, which is expected for urea water management. In a SCR system, catalyst is installed in the exhaust pipe and urea is sprayed from the upstream and then decomposed by the heat of exhaust gas and becomes ammonia. Through catalyst reactions, NOx and ammonia are converted to harmless nitrogen and water. This SCR system enables 40% of urea water to be efficiently treated.
