Vanadium empowers the polarity
Building of agglomerates of asphaltenes
Agglomerates are hard to reverse
Let's look at some models and lab tests
Single asphaltene
Four asphaltenes
building up to an agglomerate
Disperse Asphaltenes
Reduce Polarity
Avoid Asphaltenes building up to an
agglomerate
Excellent dispersing aromatics are

Which vessels / engines do you have in mind?
Combustion Catalyst MERGI
The fuel saving alone more than pays for the
cost of using MERGI
Complete Combustion gives:
Less maintenance

Type of fuel : Diesel Oil.
Immediately: clean exhaust and slow steaming was now possible.
Changes during 7 weeks : cleaner boiler, rpm raised from 850 to
860.
Cylinder temperature: decrease 10 dg.
Changes next 6 weeks : cleaner filters, turbo pressure raised 1,75
- 2,0 bar. Max cylinder temp difference : now 15 dg, before 60 dg.
Time between cleaning lube oil purifier slowly increased 100%
Inspection of injectors : before 2000 h. After 6000 h.
Lower fuel consumption. This mainly because it was now possible
to run the engine at any load without having soot problems.
