Reasons to Buy Nalco EC5624A PLUS Reasons to Buy Nalco EC5624A PLUS Ethanol Corrosion InhibitorEthanol Corrosion Inhibitor

• Nalco has 40+ years of experience formulating fuel additives - including ethanol corrosion inhibitor– Voting member of ASTM D-2 – Active RFA Technical Committee member

• Nalco is a major global supplier for fuel additives to refiners, terminal operators and fuel marketers– Nalco’s top 5 global customers include Exxon-

Mobil, BP and Chevron

Competence


• EC5624A PLUS is a better formula:– Highly refined, better consistency components – Allows for a low, but effective recommended treat rate

of 5-15 PTB– Provides long term pHe buffering capability– Outstanding solubility in denaturant and ethanol– Ultra low sulfur content– Excellent inhibitor cold flow properties

No need for heated storage– USA EPA registered – All components are listed on the Canadian DSL

Quality

EC5624A PLUS: 2EC5624A PLUS: 2ndnd generation generation ““fluorescently traced” ethanol corrosion inhibitorfluorescently traced” ethanol corrosion inhibitor

Innovation

• Allows for fast, easy and accurate determination of inhibitor treat rate in E-100 to E-85

• Uses an inexpensive handheld instrument for measurement

• EC5624A PLUS can be added to ethanol or to denaturant

• When used as directed, EC5624A PLUS will not impact the color of fuel ethanol

• EC5624A PLUS will not impact the color of gasoline even at 100’s of times the recommended dosage

• Calibration is not affected by denaturant• Does not interfere with major oil “brand

markers”

22ndnd Generation EC5624A PLUS continues the Generation EC5624A PLUS continues the success of EC5624ATRsuccess of EC5624ATR

• EC5624A PLUS provides:– Improved pHe boosting power vs EC5624A &

EC5624ATR Proven to properly buffer low pHe ethanol for 16+ weeks

@ 10 PTB

– Lower treat cost Now competitive with the low cost leader

– Improved additive cold flow

– Same regular, on-site service to help you maintain

ethanol quality and control inhibitor treat cost

– Magellan Pipeline Approved at 10PTB!

Continuous Improvement

Treat Rate Management in the Palm of Your Treat Rate Management in the Palm of Your HandHand

• Ethanol corrosion inhibitor treat rate control has

always been a challenge – Most inhibitor suppliers are just a voice on the phone.

• EC5624A PLUS enables ethanol producers to precisely manage corrosion inhibitor dosage. – No more wasteful over dosing. – No more returned loads due to under dosing. – Consistent inhibitor concentration is now made fast,

easy and accurate

Industry Leader

Is there really a problem with inhibitor treat rate

**The RFA recommends pHe stability testing for 16 weeks along with corrosion testing initially and after 16 weeks storage. In the corrosion tests, the candidate ethanol is evaluated as an E10 blended using gasoline with a E0 rating of “C”. In these tests, we used a gasoline with an E0 rating of “E” because a “C” NACE fuel could not be found. By definition, NACE “E” is 50-300% more corrosive than “C” NACE gasoline. EC5624A PLUS are approved for use in ethanol shipped to Magellan Pipeline @ 10 PTB.

Is EC5624A PLUS compatible with my current program?

Nalco EC5624A PLUS CompatibilityNalco EC5624A PLUS Compatibility

• EC5624A PLUS is compatible with all other known ethanol corrosion inhibitors marketed in North America, when the additives are blended into fuel ethanol.

• EC5624A PLUS “additive” is compatible with Innospec DCI-11 and Corr Pro656 in additive storage. – We recommend at least 67% Nalco content in

additive storage to maintain tracer accuracy

• EC5624A PLUS may be compatible in storage with other ethanol corrosion inhibitors. – This can usually be determined quickly via

testing.

Seamless Change


• Zero Defect Delivery prevents delivery mishaps– Improved Safety– Less chance of a reportable chemical spill– Used in all small bulk deliveries– Used in all on-site tote delivery/transfers

• Nalco offers regular on-site service and support by a qualified sales engineer – We make inhibitor a priority at your facility

“We are not just a voice on the phone”
