The Emigreen® MINOx SCR system reduces NOx emissions produced by marine diesel engines to below IMO Tier III limits. In fact, to some extent the system can be configured to exceed international maritime standards to meet specific local requirements. 

The benefits of an Emigreen® SCR system

– NOx reduction that meets or exceeds IMO Tier III limits
– Can be installed in new ships and as retrofit
– Easy to maintain by the crew

Why install an SCR system?

Diesel combustion engines emit nitrogen oxides (NOx).

While not immediately harmful at normal environmental concentrations, these poisonous gases are ultimately detrimental to human, animal and plant health. In hot weather, higher levels of NOx pollution contribute to the formation of smog.

An SCR system helps prevent this by significantly reducing nitrogen oxide emissions.

How our SCR system works

Our SCR catalytic converter reduces nitrogen oxide emissions.

1: A urea solution such as AdBlue is injected (sprayed) into the exhaust system
2: The water evaporates and the urea is converted into ammonia
3: The ammonia reacts with the nitrogen oxides in the exhaust stream
4: As they pass through the catalytic converter, the gases are converted into inert nitrogen and water vapour.

Emigreen® specialises in built-in SCR unit installation in small spaces

The Emigreen® SCR system is more compact than the alternatives.

Our systems can be cleverly tailored to make the best use of the available space. The integrated silencer in an Emigreen® SCR unit eliminates the need for the existing silencer.

This makes it possible to do more in less space. Our SCR solution can also be installed as a retrofit, even in spaces that look too small.

And where the ship design allows, one of our standard systems may be the most effective solution.

Emigreen® is the leading innovator in the field of Selective Catalytic Reduction (SCR) and Diesel Particle Filters (DPF).

In the maritime world, we work with companies that operate inland shipping, coastal and sea going vessels. Retrofit is one of our key activities. We ensure that the ships we deal with are retrofitted in the most efficient and effective way.

Our 15 years of experience and constant drive to improve have led to the development of exhaust gas aftertreatment solutions for the first hybrid dry cargo vessel, MVS Goblin. Moreover, thanks to our systems, MCS Anda is the cleanest Dutch inland vessel. We reduced the emission levels to be compliant with EU Stage IV norm.
