DeNOx SCR Exhaust Gas Cleaning

A wide range of DeNOx systems for marine applications, from small boats and motor Yachts to big ships, to remove Nitrogen Oxides from diesel engine exhaust gas, using SCR (Selective Catalytic Reduction) technology, up to 25 MW engine output. Our DeNOx SCR, and all the catalytic solutions, are designed and engineered by CatEMission. Benefits Designed to meet IMO Tier III and EU Stage V regulations. Highly configurable to suit diverse installation and operational scenario with the most compact size. Wide range of power covered covered, up to 25MW. Extended lifecycle thanks to catalysts elements based...

Ensure compliance Ecospray solution to support Diesel Engines compliance with NOx emission control standards as defined in Regulation 13 of MARPOL Annex VI is based on Selective Catalytic Reduction aftertreatment (SCR). SCR uses reductant to treat the exhaust gases to reduce the amount of NOx emitted. The reductant, Ammonia in the form of Urea solution, is injected into the exhaust gas stream and mixed with the exhaust gases prior to entering the SCR reactor. The chemical reactions take place in the catalyst’s elements, where Ammonia reacts with the NOx in the exhaust gases resulting in Nitrogen...

IMO Tier III and EPA Tier IV compliance 18 With the entry into force of the International Marine Organization’s (IMO) NOx Tier III limits, the regulations governing marine emissions became significantly more stringent, lowering the permissible NOx emissions in NOx Emissions Control Areas (NECA) by about 75% in comparison to IMO Tier II. Existing Emission Control Areas as of January 2021 include the Baltic Sea, the North Sea, the North American ECA, including most of US and Canadian coast, the US Caribbean ECA with Puerto Rico and the US Virgin Islands. Others are under evaluation (e.g. the Mediterranean...

Suitable for new build and retrofit installation. HFO / MDO / MGO compatible with SOx scrubber systems and boiler/silencers (existing or tailor-made). Ecospray patented high-efficiency spraying lances and nozzles. High efficiency with limited Ammonia slip, low back pressure (<20mbar).
