  • Available in vertical or horizontal configurations

NOx Emissions for ships in areas called ECA (Emission Control Area), Regulation 13This regulation requires a DeNOx system for engines above 130kW.
We reduce engine flue gas NOx values below the limit values specified in regulation 13 with the DeNOx systems we specially design for each project according to the engine room dimensions.
Our main services include:

  • NOx emission reduction up to the desired level
  • Exhaust system sound reduction 35 dB(A)
  • three-way catalyst
  • Ammonia slip catalyst
  • automation
  • Supervision services
  • Hydrocarbon emission reduction (HC)
  • Carbon monoxide emission reduction (CO)
  • diesel particulate filter
  • Continuous Emissions Monitoring System (CEMS)
  • commissioning

Regulation 13

Nox Regulation for Ships Marpol Annex VI, Regulation 13
The regulation issued in 1997 was amended in 2005. It applies to engines above 130 kW operating in Emission Control Areas (ECAs), subject to the NOx limits shown below. Current engine technology cannot meet Tier III limits without an exhaust aftertreatment system.
