1. Enviro
2009

4. More and more
yacht owners are
environmental
aware

15. Soot
NOx, SOx, CO, HC reduction
Noise attenuation & vibration control
Back pressure control
Temperature reduction
Available space
Within budget
Regulations
On time

16. How
Do
You
Go
Green
in Exhausts

17. Emission - Reduction

18. Let’s talk about Soot:
Particle
Particle Matter (PM)
Matter (0.01-0.08 mm) combine to
make agglomerates
(0.05-1.0 mm) Adsorbed
Vapour Phase
Hydrocarbons
Hydrocarbons
Adsorbed
Soluble Organic Hydrocarbons
Fraction (SOF)/
Particle Phase

Liquid Condensed
Hydrocarbon
Particles
Adsorbed
Sulfate with Hydration
Hydrocarbons
Sulfate (SO4)

21. How to deal
with soot?

25. Regeneration:
* Fuel
* Electrical spiral
* Additives
* Self regeneration
Nauticlean® By HUG engineering

27. How About

28. IMO rules push
engine suppliers
to reduce
NOx emission

29. Selective
Catalytic
Reduction
SCR technology can take out all NOx

30. Auxiliary &
Main engines

31. Technology is the same

32. The size and price of the
systems are quite different

33. Going green
is about making choices

34. Technology is available

35. Space & Budget
are needed to realize it

38. Low emission engines

39. New cleaning solutions

40. Different power source

41. The Ideal installation
“…in general to go “green” I suggest installing a
generator exhaust with soot filter, a catalytic
converter, and a silencer/separator.”
