Presentation Objectives
1. Illustrate how sludge forms in marine diesel fuel systems
2. The role of sludge in the process of MIC (microbially influenced corrosion)
3. How to eliminate sludge and protect systems from corrosive elements
4. Performance Implications of cleaner fuel systems
Stage 1. Attachment
Bacteria exist in fuel, water and tank lining
Free floating planktonic bacteria seek surfaces to attach themselves to
Non-uniform development
Takes minutes to start forming
Stage 2. Biofilm Growth
Sessile bacteria are anchored to the surface of the tank wall
Exopolymers are excreted by the bacteria to create external anchor sites and to protect them from the environment (colonizing)
Produce slime – exo poly-saccharides (EPS) to colonize the surface
Stage 3. Growth
Development of a complex three dimensional structure
Influenced by its environment
Develop within hours
Thickness of biofilm can range from a very thin layer to centimetres thick
pH can range from slightly to extremely acidic values
Stage 4: Biofilm properties
Extremely resistant to attack while in biofilm colonies
Biocides – ineffective with biofilms
May kill “millions” of bacteria with treatment but ineffective with biofilms
Stage 5. Sloughing Phase
Proliferation of the colonies can be dispersed into the fuel (sludge)
These colonies re-attach and seed new sites for growth
If uncontrolled, can seriously contaminate a fuel system
Filters, pumps, injectors, fuel lines
Development of anodic sites which leads to pitting corrosion
Stage 6: re-attachment
Dispersed clusters re-attach to new sites expanding the biofilm contamination
Agitated tanks can accelerate this process
New colonies form and process is repeated
What does biofilm (sludge) look like?

Marine Fuel Tank Sludge Filter Canister
What does sludge (biofilm) look like?
Filter Canister Fouled Racor
Biofilm can be opaque
Filters appear similar
Far left is plugged
Second is partially plugged
Third is partially plugged
Fourth is operating fine
Each filter weighs less as you go from left to right (biofilm increases weight of filter)
Results of progressive treatment of Fuel Right over 4 fuel bulk treatments – filters progressively cleaner

MIC
Microbial influenced corrosion refers to the influence of microorganisms on the kinetics of the corrosion of metals, caused by microorganisms adhering to the interfaces (usually called “biofilms”). Prerequisites for MIC are the presence of microorganisms. If corrosion is influenced by their activity, further requirements are: (I) an energy source (II) a carbon source (III) an electron donor (IV) and electron acceptor and (V) water.
MIC Process
Requires key elements
1. The existence of bacteria Naturally present in fuel
2. The presence of water / oxygen Present in fuel - typically delivered by fuel delivery company
Condensation / leaking / openings
3. A surface to attach to (biofilm) Tank walls
Tank linings (holidays)
Contaminants (oxides, salts etc.)
Types of Organisms Present in Biofilm
Variety of bacteria present Aerobic – such as slime forming bacteria
Anaerobic – produce organic acids
Fungi – produce organic acids
Some have the ability to substitute oxygen with oxidisable compounds
ie: Iron (Fe), Manganese, Sulfur
Anodic Sites – Pitting Corrosion
pH of “sludge” is acidic pH value varies across biofilm
Steel surface sacrifices electrons (becomes sacrificial anode)
Accelerated corrosion process (pitting) occurs in localized areas
Rate is dependent on biofilm colony
MIC Examples
Heating Oil Tank Diesel Underground Storage
How to STOP SLUDGE and MIC?
Eliminate bacteria?
Biocides can kill bacteria
Biofilm (sludge) and biocides?
Extremely resistant to attack, biocides are ineffective
Can not be “washed” from the surface
Only sandblasting to near white metal finish will rid of existing bacteria
Water/Oxygen
Control water but source is external
Steel
Protective Coatings
Coatings are prone to MIC
The ANSWER?
FUEL RIGHT® - stand alone technology
Proprietary formulation of filming amine technology NOT a conventional diesel fuel additive NOT a biocide
Release biofilm from steel surface and protect surface with filming amines Existing sludge is dissolved by Fuel Right Proven over 17 years of field experience
What are Filming Amines?
Form a protective coating Waterproof barrier
Inhibit corrosion
Isolative (electrical impedence)
Penetrate the biofilm Impeding the growth and displace existing biofilms
Dissolving the sludge back into a microscopic form to be dispersed safely into fuel and burned off.
Control deposits in the fuel system Fuel injectors
Intake valves
Fuel pump
Filters
How do they work? Inhibiting the Process
Fuel Right filming amines replace the conditioning film
Sludge is dissolved
Microscopic particles are safely released back into fuel
Filming Amine Water proof
Corrosion proof
Fuel Right Animation
Exo Poly-Saccharide “Glue”
Dissolved by Fuel Right
“melting ice”
Becomes part of fuel
Harmlessly burned off
Dark microscopic particles released into fuel
“Dark” Microscopic Particles
Degraded fuel
Result of bacteria converting it to food
Not from instability
Released into fuel
Sub-microscopic
Fuel Right prevents them from sticking to and fouling surfaces
Harmlessly burned off as fuel
Protected System
Fuel Right coats all surfaces
Alkaline pH
Helps to neutralize acidic components (stabilizing)
Hydroperoxides
Prevents further formation of biofilms
Before Treatment
Water present
Diesel Fuel
Biofilm able to form
Sludge growth
Acidic pH
After Treatment
Fuel Right treatment
Filming amines coat jar
Biofilm unable to form
Existing sludge dissolves
Water remains
Fuel Right and Fuel Filters
Clean Fuel = less strain on fuel filter
Filming amines also coat filter cartridge and all other fuel system surfaces (fuel lines, pumps etc.)
Extend filter life 2-3x
Eliminate filter plugging due to sludge
Fuel Right Results!
Protects Nozzle/Injectors 7 year corrosion test
Fuel Right & Your Engine
Coats complete fuel system
Protects injectors against fouling
Ensures optimal atomization
Optimal ignition
Impacts fuel economy Keeping system clean ensures optimal fuel performance
Filming amines have a natural detergency affect
Implications
Higher tier engines have strict tolerances
Fuel quality is critical – especially in emergency supply situations where fuel is stored long-term
Fuel additives modify fuel properties (lubricity, cold flow pour point, cetane boost, anti-waxing & gelling) but do not “clean” the system
Filming amine technology protects the system from biofilm attack
Smaller micron filters are more prone to biofilm clogging
Fuel Right filming amines dissolve the biofilm – clean fuel
Overall better fuel system performance

• “In August 2008, we began treating the Meredith with Fuel Right and about two months later we began treating the Christian. It is fair to say that we have observed significant reduction in the quantity of fuel filters used as a result of our consistently treating both vessels. In May 2010, both the Meredith and the Christian were brought in for dry dock. When we inspected the fuel tanks, we were pleasantly surprised to see that the walls and the floors were remarkably clean by comparison to what we normally see when the fuel tanks are inspected – a real savings to us both in terms of time and materials.”

References • “One of our tugs in Baltimore had a tank that must have contained a lot of sludge. I knew
that we were holding a good deal of water but we were unable to get anything out of the lower draw. Two weeks after we treated the tank with Fuel Right, we began to see a dribble and two weeks after that, we discharged 400 gallons of water from the lower draw. I don’t know how it worked, but this product helped us achieve our objective.”

• We received a bad load of diesel and almost immediately started to see filter plugging in one of our boats. As a result of this, we were changing fuel filters every 24 hours. Shortly after treating with Fuel Right, the problem dissappeared and things were back to normal. Had we not been introduced to Fuel Right, my next step would have been to dispose of the fuel and clean the tanks. Fuel Right saved me thousands of dollars – Thanks”
