Reduction of the harmful NO pollutants emitted from the ship engines using high-pressure selective catalytic reduction system.

Various techniques are used to reduce harmful pollutants such as NO emissions from ships. Selective catalyst reduction (SCR) systems are the most effective technique used to reduce NO emissions. In this study, the effects of an SCR reactor on NO emissions and performance in high-pressure selective catalytic reduction (HP-SCR) systems were investigated numerically.
