NOx removal in Marine Engines

Reduce NOx (nitrogen oxide, nitrogen dioxide) emissions from ship's engines with NOxCare® Marine. NOxCare Marine is a complete portfolio of reagents, Selective Catalytic Reduction technology (SCR) technology and services.

Marine NOx Regulations

NOx emissions from shipping are increasingly regulated in NECAs (NOx Emission Control Areas). From 2016, new IMO Tier III requirements will require new builds to comply with NOx emission requirements in territorial waters. Canadian authorities and the United-States Environment Protection Agency (EPA) is already implementing a North American and U.S. Carribean NECA imposing stringent NOx emission limits. Other NECAs are bound to follow, as IMO regulations will be adopted around the globe. Yara’s NOxCare Marine is the total solution for ship owners and operators seeking to meet these new and emerging regulatory requirements.

SCR Systems – A Proven Technology

  • SCR systems reduce nitrogen oxide and nitrogen dioxide emissions (NOx emissions).
  • SCR systems can achieve more than 99% NOx emission reduction from fuel combustion processes.
  • SCR Technology is proven, compact and commonly used in hundreds of vessels, both on propulsion and auxiliary engines. Yara has delivered more than 1300 systems on board more than 350 vessels and is by far the market leader to the maritime industry.
  • SCR systems are also used to control NOx from land-based engines (heavy-duty vehicles, industrial combustion plants).

Our NOxCare Marine SCR systems are designed to be cost-efficient, robust, compact and easy to operate. Whether planning a new build or retrofitting an existing ship, our experts can help you ensure your vessel complies with maritime environmental regulations for removal of NOx.
