Overview

The use of ethanol as a gasoline additive has increased dramatically over the past few years and will likely continue to increase. For fuel blenders, this means an added challenge to avoid an incorrect blend that could lead to regulatory fines, loss of customer confidence and damage to equipment. A quick on-site analysis with a portable mid-infrared based analyzer, such as the InfraCal 2 Ethanol Blend Analyzer shown in the photo, can help fuel blenders quickly flag out-of-spec product and ensure the final blend meets specifications.  

Biodiesel is a renewable diesel fuel that is also known as FAME (fatty-acid methyl ester) in the European Community. It is made from animal fats, vegetable oils or recycled restaurant greases. Biodiesel has the advantage that it works just as well as normal diesel fuel, but the combustion process expels lower concentrations of toxic emissions.

In most applications, biodiesel is used as a fuel additive at 1:4 proportions (20%) with petroleum diesel. Spectro Scientific has analytical instruments that can be applied as quality control methods to verify that delivered biodiesel blend ratio, glycerin content and contaminants are as specified.


Challenges

In a published paper on biodiesel blend quality submitted by the National Renewable Energy Laboratory, the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For fleet managers, an incorrect blend can mean a total shutdown of operations. On the regulatory side, the increase in fuel costs combined with the financial rewards of tax rebates and credits have allowed for shady characters to take advantage of inadequate testing programs by adding less biofuel than stated or adding other components to extend the fuel such as pure vegetable oil, jet fuel or kerosene.

Cold weather performance, engine performance, warranty issues, and tax incentives are all motivations to having an accurate, portable and reliable biodiesel blend measurement. A quick analytical measurement method to assess the blend ratio can be a valuable asset for fuel distributors, engine manufacturers, fleet operators, and regulatory agencies.

The InfraCal 2 Biodiesel Blend Analyzer and the InfraCal2 Ethanol Blend Analyzer are the ideal solution where a quick, accurate, on-site measurement is required and a single, repetitive biodiesel blend analysis is needed. The InfraCal 2 is based on proven IR technology, originally developed by Wilks, and used by regulatory agencies and fuel terminals worldwide.  


Typical Tests

The InfraCal 2 Biodiesel Blend Analyzer for measuring percent biodiesel in diesel is the ideal solution where a quick, accurate, on-site measurement is required. With a measurement range of 0 – 100% biodiesel in diesel and an accuracy of +/- 0.2, the InfraCal 2 is based on proven IR technology developed by Wilks and used by regulatory agencies and fuel terminals worldwide. The compact, easy-to-use InfraCal 2 Biodiesel Blend Analyzer measurement results are comparable to both ASTM D7371 and EN 14078.

If you need a quick and easy test that can be performed in the field in minutes the InfraCal 2 is the choice for you.
