Some myths about ULSD
   (“Truths” to follow later)
Myth 1: ULSD Fuel is unstable, which 
 leads to sludge. Therefore, you should 
  add stabilizers to your ULSD fuel to 
        prevent sludge formation.
Myth 2: Algae are a problem in 
            ULSD
Myth 3: The more rapidly you turn 
 your fuel over, the less sludge and 
       fouling there will be.
High Turnover Marketing Techniques  


       Quote from Fuel Dealer
          Advertisement

“All our fuels are filtered prior to leaving 
our bulk plant. With our fuels you're always 
assured of "Fresh Diesel Fuel" because of 
the rapid turnover of our products.”

                                            13
Myth 4: I have my fuel polished and 
the contractor shows me clean fuel….. 
    Therefore my tanks are clean.
Myth 5: Biocides are the answer 
because, if I kill the Bugs, they can’t 
          cause problems. 
Myth 6: If I use Detection Kits I can
detect Microbes and Fungus Growth. Then
  I can add Biocides to kill them and the
          problems will go away.
Myth 7: You can use an additive to 
remove all water from your tanks so 
bugs can’t grow and cause problems.

What is different about 
         ULSD? 

What causes fouling, sludge 
 and corrosion in ULSD?
Each “generation” of #2 Fuel has
unique properties and challenges
• Straight run distillate (prior to ’60’s) – excellent
  fuel but limited supply
• Cracked, high-sulfur #2 (’60’s-80’s) – unstable
• Low-Sulfur #2 (into 21st century) – excellent fuel,
  stable, air pollutant
• ULSD (since 2000) – excellent fuel, stable, low-
  pollution, poor lubricity, low conductivity
All generations of #2 fuel have
  certain common properties:
• They are mixtures of dozens – maybe
  hundreds – of different hydrocarbon
  molecules
• They contain paraffin and thus have cold-
  flow issues
• They support growth of certain bacteria,
  yeasts and molds when water is present
Regarding sludge, fouling and
corrosion, the problem is not the
fuel, but rather the “critters” that
         grow in the fuel.
Biofilms 101




                                                                                            23
 Taken from: •“Simple methods for the investigation of the role of biofilms in corrosion” Bio-
We store and transport fuels in
open or vented containers.
Because of this, nearly all fuels
contain
    - water, and
    - microbes (“critters”)
WATER IN FUEL




                25
Water can be present in fuel as:

• Dissolved water (invisible, not a problem)
• Suspended water (emulsion or haze)
• Free water layer (in bottom of tank)
Emulsions or suspended water:
- Do not form in “pure” fuel
- Are formed by chemical surfactants
       (from additives – or from microbes)
- Support growth of “critters”
- Can cause rusting of steel/cast iron
- Are usually (but not always) bad news
Microbes in #2 Fuel …

1.   Include bacteria and fungi
      (yeasts, molds)

2.   May come from the air, water, dirt
     and debris
3.   Are always present in stored fuels

4.   Cause problems, including sludge,
     fouling, and corrosion.

                                          28
The entire Supply Chain may be contaminated

SLUDGE




         30
In Higher-Sulfur Fuels
the Sludge was Black and “Slimy”




                                   31
Classic, black sludge consists of:
•   Water
•   Degraded (solid) fuel
•   Trapped particles/debris
• Bacterial slime

             Results Of MIC           33
Sludge and Fouling in ULSD may be
    different – reddish instead of black




First Signs are Slow Pump, Dispenser Issues
   and Need to Replace Filters Frequently

Corrosion in ULSD Systems




                            36
How Long Does It Take
for Corrosion to Occur?




                                                   37
  This Corrosion occurred in less than 18 months
To Review: Corrosion Will Occur…




• When Free Water is Present
• When Sludge grows on metal surfaces
                                        38
The Battelle Report:

• Studied six underground ULSD tanks to
  attempt to understand corrosion occurring
  in those systems
• Concluded that the corrosion was probably
  caused by acetic acid generated by bacteria
  from ethanol contaminant in the fuel
• Did not provide “good science” due to
  inadequate funding.
                                                39
Questions So Far?




                    40

Where does fuel polishing fit into
         this picture?

Fuel Polishing
If you see this:          Then you have this:




                                                44
Fuel Polishing
Benefits:

a. Removes “Free Water”- this part is best value of
  polishing.

b. Removes Loose “Debris”- Metal Sulphide-coffee
  grounds, Aluminum Oxide-sandy grit, Common Dirt.

c. Removes Bottom Sludge- Asphaltene, bacterial slime.

d. Immediate Gratification- Pretty fuel samples.

e. Solves filter plugging issues “Today”!                45
Fuel Polishing
Concerns:

1.   Nothing More Than Industrial Filtration for loose
     particulate and water. Expensive filters, Disposal.
2.   Does Not Address Suspended or Emulsified Water, nor
     acid value caused by bacteria waste.
3.   Hard to reach area limited without expensive or
     dangerous access techniques .
4.   Does not remove “Live” embedded bacteria in tank
     walls, fuel lines or pumps.
5.   Bacteria re-growth never stops, even when Free Water is
     gone.
6.   Not a long term solution.
                                                          46

How About Tank Cleaning?
49
Small tanks (≤ 2000 Gal.)
Usually cleaned from outside.
   (Difficult to do well.)

 Larger tanks (≥ 5000 Gal.)
Usually require manned entry.
(Expensive, safety concerns.)
If scraped and shoveled only,
cleaning is marginal, re-growth
       of sludge is rapid.
High-pressure water blast is
better – but expensive – and re-
  growth is still fairly rapid.
Water Blast followed by Sand
  Blast is better yet – but even
more expensive – and tank is still
 not sterile so re-growth occurs
over time. (Also, sand blasting is
   destructive to tank walls.)
Regardless of method used,
cleaning is not perfect, re-growth
  occurs, and there is the added
  cost of disposal of hazardous
       waste (sludge, etc.)
Summary: Benefits of Tank
           Cleaning

• Provides operating benefits for some time,
  which depends on method(s) used.

• Is the surest way to quickly get rid of
  accumulated sludge in tank.
Summary: Down-side of Tank
             Cleaning
•   Expensive
•   Requires extended tank outage
•   May have safety concerns for workers
•   Generates hazardous waste for disposal
•   Not a permanent fix – will have to be done
    again and again

 What are the best answers for
sludge, fouling and corrosion in
         ULSD tanks?
But First… the “truths”
associated with common myths.
Myth 1: ULSD Fuel is unstable, which
leads to sludge. Therefore, you should add
stabilizers to your ULSD fuel to prevent
sludge formation.

Truth: ULSD is usually very stable, and
studies have shown that chemical stabilizers
do little or nothing to stop sludge and
corrosion.
Myth 2: Algae are a problem in ULSD


Truth: Algae are microscopic plants
that need sunlight. Therefore they are
one type of “critter” not found in fuel
systems.
Myth 3: The more rapidly you turn your
fuel over, the less sludge and fouling there
will be.
Truth: Bacteria are limited in what they can
use in the fuel. Turning it over rapidly
supplies more food for their growth – and
therefore more growth. (Look at how fast
fuel filters grow sludge!)
Myth 4: I have my fuel polished and
the contractor shows me clean fuel…..
Therefore my tanks are clean.


Truth: Clean, filtered fuel does not
necessarily mean a clean tank. How did
the process remove sludge and water
from the bottom of the tank?
Myth 5: Biocides are the answer
because, if I kill the Bugs, they can’t
cause problems.


Truth: biocides usually can’t penetrate
into the biofilm (slime) to reach and kill
the harmful bacteria – and, even if they
did, they would do nothing to stop
corrosion.
Myth 6: If I use Detection Kits I can detect
Microbes and Fungus Growth. Then I can add
Biocides to kill them and the problems will go
away.
Truth: Test kits are a good way to sell biocides,
because they almost always show living critters
in fuel. The microbes they measure are free-
floaters – most of whom are doing nothing of
concern. Kits generally don’t sample the biofilm
on the walls and bottom of the tank – and, even
if they did, biocides don’t work there anyway!
Myth 7: You can use an additive to
remove all water from your tanks so bugs
can’t grow and cause problems.
Truth: While some additives do contain
alcohols that can “hide” water in fuel,
they do not remove it from the system.
This “wet” fuel is now more corrosive
than was water alone (to tanks and
engines) – and great food for bacteria!
So, how do we stop sludge,
fouling and corrosion in ULSD?

      (Thought you’d never ask!)
The Answer: With Dual Filming
     Amine Technology
The Dual Filming Amines in
          Fuel Right :
                    ®

• Dissolve existing slime into the fuel, where it
  passes through and burns up harmlessly (i.e. no
  more old sludge)
• Coats all wetted surfaces in the system to preclude
  bacterial attachment – thus slime formation (i.e. no
  new sludge)
• This coating also protects steel and iron against
  corrosion – even if there is free water present!
And there’s more good news…
• The amines clean injectors and lower fuel surface
  tension – thus improving atomization and reducing
  unburned fuel and smoke,
• The amines act as micro-emulsifiers, pulling some
  of the water present into the fuel as a slight haze –
  where it goes through and produces a little steam
  without causing corrosion or other problems,
• The amine film acts as a lubricating film and
  greatly reduces metal wear in pumps, etc.
In other words,
• Dirty tanks clean up,
• Clean tanks stay clean, and
• Corrosion of wetted surfaces stops within
  days following first treatment – even though
  the existing sludge takes some time to go
  away
• Diesel systems work the way they are
  supposed to!

Fuel Right – Does it Work?




                             72
The Battelle Report revisited
(raw, unedited version as originally issued by Battelle)
• Tanks tested for “total DNA” = relative amount of
  fouling
• One with no apparent problems yet tested very
  high in total DNA
• One treated twice in prior year with well-known
  biocide tested very high in total DNA
• One treated once 6 months prior with “biocide”
  [sic] Fuel Right tested very low in total DNA

  • 9. Some myths about ULSD (“Truths” to follow later)
  • 10. Myth 1: ULSD Fuel is unstable, which  leads to sludge. Therefore, you should  add stabilizers to your ULSD fuel to  prevent sludge formation.
  • 13. High Turnover Marketing Techniques   Quote from Fuel Dealer Advertisement “All our fuels are filtered prior to leaving  our bulk plant. With our fuels you're always  assured of "Fresh Diesel Fuel" because of  the rapid turnover of our products.” 13
  • 16. Myth 6: If I use Detection Kits I can detect Microbes and Fungus Growth. Then I can add Biocides to kill them and the problems will go away.
  • 18. Bob Tatnall, P.E. • For 30 yrs. – internal consultant at DuPont  (equipment failures, corrosion, biocorrosion),  group leader in biocorrosion research at DuPont • Co-founder NACE committee on MIC • Published >40 papers and articles • Developed Fuel Right® treatment for #2 fuels to  prevent sludge, fouling and corrosion in fuel  systems
  • 19. What is different about  ULSD?  What causes fouling, sludge  and corrosion in ULSD?
  • 20. Each “generation” of #2 Fuel has unique properties and challenges • Straight run distillate (prior to ’60’s) – excellent fuel but limited supply • Cracked, high-sulfur #2 (’60’s-80’s) – unstable • Low-Sulfur #2 (into 21st century) – excellent fuel, stable, air pollutant • ULSD (since 2000) – excellent fuel, stable, low- pollution, poor lubricity, low conductivity
  • 21. All generations of #2 fuel have certain common properties: • They are mixtures of dozens – maybe hundreds – of different hydrocarbon molecules • They contain paraffin and thus have cold- flow issues • They support growth of certain bacteria, yeasts and molds when water is present
  • 22. Regarding sludge, fouling and corrosion, the problem is not the fuel, but rather the “critters” that grow in the fuel.
  • 23. Biofilms 101 23 Taken from: •“Simple methods for the investigation of the role of biofilms in corrosion” Bio-
  • 24. We store and transport fuels in open or vented containers. Because of this, nearly all fuels contain - water, and - microbes (“critters”)
  • 26. Water can be present in fuel as: • Dissolved water (invisible, not a problem) • Suspended water (emulsion or haze) • Free water layer (in bottom of tank)
  • 27. Emulsions or suspended water: - Do not form in “pure” fuel - Are formed by chemical surfactants (from additives – or from microbes) - Support growth of “critters” - Can cause rusting of steel/cast iron - Are usually (but not always) bad news
  • 28. Microbes in #2 Fuel … 1. Include bacteria and fungi (yeasts, molds) 2. May come from the air, water, dirt and debris 3. Are always present in stored fuels 4. Cause problems, including sludge, fouling, and corrosion. 28
  • 29. The entire Supply Chain may be contaminated 29
  • 30. SLUDGE 30
  • 31. In Higher-Sulfur Fuels the Sludge was Black and “Slimy” 31
  • 32. Classic, black sludge consists of: • Water • Degraded (solid) fuel • Trapped particles/debris • Bacterial slime 32
  • 33. Microbiologically Influenced Corrosion. (MIC) Results Of MIC 33
  • 34. Sludge and Fouling in ULSD may be different – reddish instead of black First Signs are Slow Pump, Dispenser Issues and Need to Replace Filters Frequently 34
  • 35. 35
  • 36. Corrosion in ULSD Systems 36
  • 37. How Long Does It Take for Corrosion to Occur? 37 This Corrosion occurred in less than 18 months
  • 38. To Review: Corrosion Will Occur… • When Free Water is Present • When Sludge grows on metal surfaces 38
  • 39. The Battelle Report: • Studied six underground ULSD tanks to attempt to understand corrosion occurring in those systems • Concluded that the corrosion was probably caused by acetic acid generated by bacteria from ethanol contaminant in the fuel • Did not provide “good science” due to inadequate funding. 39
  • 42. Where does fuel polishing fit into this picture?
  • 43. Fuel Polishing Capt. Tom Folkesson Oceanview Marine Services, LLC 43
  • 44. Fuel Polishing If you see this: Then you have this: 44
  • 45. Fuel Polishing Benefits: a. Removes “Free Water”- this part is best value of polishing. b. Removes Loose “Debris”- Metal Sulphide-coffee grounds, Aluminum Oxide-sandy grit, Common Dirt. c. Removes Bottom Sludge- Asphaltene, bacterial slime. d. Immediate Gratification- Pretty fuel samples. e. Solves filter plugging issues “Today”! 45
  • 46. Fuel Polishing Concerns: 1. Nothing More Than Industrial Filtration for loose particulate and water. Expensive filters, Disposal. 2. Does Not Address Suspended or Emulsified Water, nor acid value caused by bacteria waste. 3. Hard to reach area limited without expensive or dangerous access techniques . 4. Does not remove “Live” embedded bacteria in tank walls, fuel lines or pumps. 5. Bacteria re-growth never stops, even when Free Water is gone. 6. Not a long term solution. 46
  • 47. Stan Smith (“Smitty”) • ’73-’88 - Owned Anthony Oil, Commercial Fuel Sales and Service • “88-Present - Owns Atlantic Bulk Carriers, Delivers fuel, lubricants and water to ships; Removes “sludge” and disposes of or recycles; Operates No. Carolina to Maine
  • 48. How About Tank Cleaning?
  • 49. 49
  • 50. Small tanks (≤ 2000 Gal.) Usually cleaned from outside. (Difficult to do well.) Larger tanks (≥ 5000 Gal.) Usually require manned entry. (Expensive, safety concerns.)
  • 51. If scraped and shoveled only, cleaning is marginal, re-growth of sludge is rapid.
  • 52. High-pressure water blast is better – but expensive – and re- growth is still fairly rapid.
  • 53. Water Blast followed by Sand Blast is better yet – but even more expensive – and tank is still not sterile so re-growth occurs over time. (Also, sand blasting is destructive to tank walls.)
  • 54. Regardless of method used, cleaning is not perfect, re-growth occurs, and there is the added cost of disposal of hazardous waste (sludge, etc.)
  • 55. Summary: Benefits of Tank Cleaning • Provides operating benefits for some time, which depends on method(s) used. • Is the surest way to quickly get rid of accumulated sludge in tank.
  • 56. Summary: Down-side of Tank Cleaning • Expensive • Requires extended tank outage • May have safety concerns for workers • Generates hazardous waste for disposal • Not a permanent fix – will have to be done again and again
  • 57. Bob Tatnall What are the best answers for sludge, fouling and corrosion in ULSD tanks?
  • 58. But First… the “truths” associated with common myths.
  • 59. Myth 1: ULSD Fuel is unstable, which leads to sludge. Therefore, you should add stabilizers to your ULSD fuel to prevent sludge formation. Truth: ULSD is usually very stable, and studies have shown that chemical stabilizers do little or nothing to stop sludge and corrosion.
  • 60. Myth 2: Algae are a problem in ULSD Truth: Algae are microscopic plants that need sunlight. Therefore they are one type of “critter” not found in fuel systems.
  • 61. Myth 3: The more rapidly you turn your fuel over, the less sludge and fouling there will be. Truth: Bacteria are limited in what they can use in the fuel. Turning it over rapidly supplies more food for their growth – and therefore more growth. (Look at how fast fuel filters grow sludge!)
  • 62. Myth 4: I have my fuel polished and the contractor shows me clean fuel….. Therefore my tanks are clean. Truth: Clean, filtered fuel does not necessarily mean a clean tank. How did the process remove sludge and water from the bottom of the tank?
  • 63. Myth 5: Biocides are the answer because, if I kill the Bugs, they can’t cause problems. Truth: biocides usually can’t penetrate into the biofilm (slime) to reach and kill the harmful bacteria – and, even if they did, they would do nothing to stop corrosion.
  • 64. Myth 6: If I use Detection Kits I can detect Microbes and Fungus Growth. Then I can add Biocides to kill them and the problems will go away. Truth: Test kits are a good way to sell biocides, because they almost always show living critters in fuel. The microbes they measure are free- floaters – most of whom are doing nothing of concern. Kits generally don’t sample the biofilm on the walls and bottom of the tank – and, even if they did, biocides don’t work there anyway!
  • 65. Myth 7: You can use an additive to remove all water from your tanks so bugs can’t grow and cause problems. Truth: While some additives do contain alcohols that can “hide” water in fuel, they do not remove it from the system. This “wet” fuel is now more corrosive than was water alone (to tanks and engines) – and great food for bacteria!
  • 66. So, how do we stop sludge, fouling and corrosion in ULSD? (Thought you’d never ask!)
  • 67. The Answer: With Dual Filming Amine Technology
  • 68. The Dual Filming Amines in Fuel Right : ® • Dissolve existing slime into the fuel, where it passes through and burns up harmlessly (i.e. no more old sludge) • Coats all wetted surfaces in the system to preclude bacterial attachment – thus slime formation (i.e. no new sludge) • This coating also protects steel and iron against corrosion – even if there is free water present!
  • 69. And there’s more good news… • The amines clean injectors and lower fuel surface tension – thus improving atomization and reducing unburned fuel and smoke, • The amines act as micro-emulsifiers, pulling some of the water present into the fuel as a slight haze – where it goes through and produces a little steam without causing corrosion or other problems, • The amine film acts as a lubricating film and greatly reduces metal wear in pumps, etc.
  • 70. In other words, • Dirty tanks clean up, • Clean tanks stay clean, and • Corrosion of wetted surfaces stops within days following first treatment – even though the existing sludge takes some time to go away • Diesel systems work the way they are supposed to!
  • 71. What Fuel Right® customers say 1. Easy To Use 2. No Special Handling Requirements 3. Economical 4. Easy to Measure Success 71
  • 72. Fuel Right – Does it Work? 72
  • 73. The Battelle Report revisited (raw, unedited version as originally issued by Battelle) • Tanks tested for “total DNA” = relative amount of fouling • One with no apparent problems yet tested very high in total DNA • One treated twice in prior year with well-known biocide tested very high in total DNA • One treated once 6 months prior with “biocide” [sic] Fuel Right tested very low in total DNA

Editor's Notes

  1. Notice the Coffee Grinds From Station in Florida….we hear this a lot. From Bottom of Tanks to Filters to Dispenser
  2. Compliment of Virginia DOT…. Dan Laing……He is tracking how problem is spreading geographically.
  3. Compliment of national repair service on Fuel Tank Systems…. safety valve. Rusting. Technician Had a whole box of them. We hear about safety valves rusting shut or rusting open…. Safety concern, Causes overflow of fuel or mis- calibration Pumps Stop Working…… sound familiar
  4. Crazy……Facts are……….corrosion in C Stores and Truck Stops is growing problem and needs to be addressed.
  5. We encourage to you ask questions during presention.
  6. Talk about Sex Sells. First Impressions, But not long term solution. Marketing Poppy Cock.
  7. Biofilms Can act as glue to hold degraded fuel, debris, rust particles. That’s why they are so tough to get rid of. Leads to small problems – plugged fuel filters….which lead to bigger problems…such as corrosion. Important to understand discuss options Tank cleaning, Fuel Polishing, Water Removers, Biocides, Filming Amine Coatings
  8. The ultimate enemy… bob tatnall
  9. How many are there? been around as long as this planet. Too many to name. Some 60 + types Important to remember when it comes time for solutions.
  10. While we are focusing on on C Stores and Truck Stops.….many problems start upstream…regardless of what they tell you. Sludge, Corrosion and Tank Cleaning go on at all facilities. Battelle Report Talks about introduction of bio – fuels, cross contamination Tampa Bay Tank Wash
  11. Lets Start here….stinky, slimy, ….leads to other problems. Actually contains excrement from bugs.
  12. Bob Tatnall
  13. Remember – Fuel is transported. Pipes are dirty…So are fuel carrier trucks….. Tampa Bay Tank Wash. Had difficulty getting it out. Important to know for solving problem….Needs something to stick to. Again Bio Film acts as glue.
  14. Bob Tatnall Point 1 - How it Effect C Store Point 2 - Your Call
  15. Drivers and Customers Complain about slow pumps, leaking nozzles, Workers complain about metering system. Dispenser Repair companies try different things, most don’t work and end up having to return….drives costs up. News works it way up to management, then to Associations. Associations want answers. Eventually Leads to Clean Diesel Fuel Alliance And Corrosion Study. Some pro active organizations….PMAA, Steel Tank Institute.…. Let’s give them some credit for trying to help the C Stores.
  16. Low Sulfur ….. Contains some Rust.
  17. Photos More Photo From Customers…..
  18. Both Field and Test Labs. We test for corrosion every day. If you are near Wilmington, we can show you our corrosion and sludge lab. Be happy to send you report.
  19. Major Cause of Tank Failure Must understand sludge need to attach to surfaces to cause problems.
  20. Bob to Elaborate on next study…. Very expensive…lots of man hours.
  21. Email them in…..
  22. Tom, Talk About Experiences Talk about three pictures Describe what would typically happen at Gas Station or Truck Stop.
  23. What are the benefits
  24. What are the Concerns Tom,
  25. Smitty – describe his knowledge and history…add some credibility
  26. Simply add a few times in first few months. Then gradually back off to planned maintenance. 1-12,000 dilution in most cases.
  27. Bob to talk about results of Fuel Right
  28. Sludge and Fouldin
