SCR is a technology which can reduce NOx in exhaust gas by a chemical reaction process. Urea solution is commonly adopted as the reductant as it decomposes into ammonia and carbon dioxide in hot gas stream.
(NH2)2CO + H2O > 2NH3 + CO2
[Urea] [Water] [Ammonia] [Carbon dioxide]
The ammonia decomposed from urea is chemically reacted with NOx at the surface of the catalyst. It is then converted to molecular nitrogen and water.
4NO + 4NH3 + O2 > 4N2 + 6H2O6NO2 + 8NH3 > 7N2 + 12H2O
SCR (Selective Catalytic Reduction) Principle
Main Features of NoNOx SCR System Main Components of NoNOx SCR System
Certification of NoNOx SCR System
SCR system and relevant certification procedure for marine application is defined by IMO.According to resolution MEPC.198(62), SCR system is considered as an engine component. Therefore, instead of separate certification of SCR system, IMO NOx verification in combination with engine is required according to Scheme A and Scheme B. NoNOx SCR system can be verified and receive IMO NOx Tier III certification at HHI-EMD test-bed according to Scheme A.
Special care is being taken to protect the environment from air pollution. IMO MARPOL NOx regulation is the dominant guideline for marine industries.IMO NOx Tier III regulations takes effect from 1 January 2016. This requires 80% less NOx emissions compared with NOx Tier I. This amount of NOx reduction is generally not achieved by the engine itself. Hence, a separate device is required to meet Tier III regulations in this respect.
NoNOx is the brand name of HHI’s SCR system. NoNOx SCR system can provide the most suitable solution for all marine applications, and can also be used in other industries as well.
