Shipping is the Source of 12% of Global NOx Emissions (≈ 21 million tons NOx/year*) NOx is a large proportion of typical diesel engine exhaust gas components: Component Component
Range Range (Vol.) (Vol.)
Nitrogen oxides (NOx)
1,000 -1,500 ppm
Sulphur oxides
30 – 900 ppm
Carbon monoxide
20 – 150 ppm
Total hydrocarbons
20 – 100 ppm
Volatile organic compounds
20 – 100 ppm
Particulate matter
20 – 100 mg/Nm3

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 down to less than 2 g/kWh compared with 17 g/ kWh in the year 2000 • A number of countries e.g. Norway have separate NOx emission legislation in effect • NOx tax in Norway is 16.69 NOK/kg NOx

BLUNOX SCR Systems are More Compact than Traditional SCR Systems and Lower Cost to Install and Operate Main components of BLUNOX DAM SCR System Typical SCR systems are air-assisted in atomising urea into the exhaust gas
Temperature sensor Optional NOx sensor
DANSK TEKNOLOGI is the only manufacturer to deliver the patented airless SCR systems Airless operation means: • No need for compressed air • No need for flow dressers, exhaust gas mixers and long urea injection pipe • No extra fuel consumption • Very compact system, which is ideal when space is limited Fewer parts means: • Low cost installation • High operating reliability • Low maintenance cost
