Nalco Tracer Technology Is Now Available in a pHe Buffering Ethanol Corrosion Inhibitor GIVING ETHANOL PRODUCERS UNPRECENDENTED POWER TO MANAGE ETHANOL QUALITY Ethanol corrosion inhibitor is vital tool for fuel marketers. Proper dosage prevents corrosion and protects fuel system components. Ethanol corrosion inhibitor dosage has long been difficult to control because there wasn’t a good way to measure inhibitor content. To solve the problem, Nalco adapted our Trasar Technology – which Nalco has used in water treatment chemicals for 20+ years to this important fuel additive. Now ethanol producers and their customers can be assured that the optimal amount of EC5624ATR has been added.

EC5624ATR provides corrosion inhibition and pHe buffering to neutralize acids
and alkalinity that can be present in fuel ethanol. However, the amount of corrosion
inhibition and pHe buffering required can vary from plant to plant and day to day:

Simple measurement.
Measurement of EC5624ATR concentration is quickly and easily accomplished
using the Nalco handheld fluorometer. The proprietary flourescing molecules
contained in the corrosion inhibitor are instantly and accurately determined.

• Calibration takes less than 1 minute.
Using the EC5624ATR chemistry and measurement systems, all ethanol producers
now have the power to easily manage cost and quality. No wasteful overdosing. No
returned loads due to under dosing.
