Reduction
of nitrogen oxide (NOx) emissions from ships due to environmental
pollution and greenhouse gas impact has been made obligatory by regulations
introduced by the International Maritime Organization (IMO). Basically, NOx
emission control mechanisms are divided into primary methods and
after-treatment methods. After-treatment methods focus on reducing NOx
emissions from the exhaust gas by various methods. In this study, the
efficiency of the urea transformation for different exhaust temperature values
for a modelled Selective Catalytic Reduction (SCR) system has been investigated
numerically. As a result of numerical model, isocyanic acid, temperature, urea
and ammonia values have been determined for Urea-Water Solutions (UWS) process
values. The study has been calculated by the computational fluid dynamics (CFD).
The numerical results obtained were confirmed by experimental studies from the
literature.
