Reduction of NOx Emissions from Shipping through BLUNOX Digital Airless Multipoint® and SCR Systems - The next generation NOx systems delivered by Scandic Diesel Services in cooperation with Dansk Teknologi servicing North America Canada, United States and Mexico (Within NAFTA)
NOx are Toxic Gasses and Stringent Emission Limits are in Place
NOx Damages our Environment and Causes Health Problems
• NO and NO2 are toxic gases
• NOx contributes to smog, acid rain and global warming
• NOx causes human respiratory problems (e.g. asthma)
Strict IMO Regulations
• Strict IMO 2016 regulation prescribe NOx limits less than 2 g/kWh compared with 17 g/kWh in 2000
• A number of countries e.g. Norway have separate NOx emission legislation in effect
• NOx tax in Norway is 15 NOK/kg NOx
SCR is the Most Effective Way to Reduce NOx and Comply with IMO Regulations
NOx can be reduced by a number of technologies:
- 20 % Basic internal engine modifications
- 35 % Exhaust gas recirculation (4-stroke)
- 50 % Direct water injection
- 70 % Humid air motor
- 95 % SCR (Selective Catalytic Reduction)
Main components of BLUNOX DAM SCR System
Typical SCR systems are air-assisted in atomising urea into the exhaust gas. DANSK TEKNOLOGI is the only manufacturer to deliver the patented airless SCR systems
Airless operation mean:
• No need for compressed air
• No extra fuel consumption
• Very compact system, which is ideal when space is limited
Fewer parts mean:
• Low cost installation
• High operating reliability
• Low maintenance cost
