Wärtsilä Netherlands: NOx Reducer (NOR)

The Wärtsilä NOx Reducer (NOR) is an emission after-treatment system based on the Selective Catalytic Reduction (SCR) technology for Nitrogen Oxide (NOx) reduction. The system is compliant with various NOx emission reduction needs, such as the IMO Tier III rules. The NOR is optimized and validated for Wärtsilä medium speed engines in terms of reliability, flexibility and size. It is available for both newbuild and retrofits and is compatible for operation on both distillate and heavy fuel oils.

The main component is the reactor, inside which is the catalyst. The highly efficient NOR system provides flexible installation and easy maintenance. The NOR is typically designed for IMO Tier III NOx emissions reduction requirements, Wärtsilä can also deliver the IMO Tier III Statement of Compliance for the full package including the engine and SCR technology. The NOR can also easily be designed to comply with other NOx emission reduction requirements.
