  • The Effect of Biodiesel Feedstocks on Infrared Blend Measurements

    This White Paper addresses the common concern among biodiesel blenders and distributors as to whether or not biodiesel made from different feedstocks such as soy, waste vegetable oil or palm oil will affect the blend measurement.  The data presented, as well as the chemistry, shows that infrared measurements offer a reliable analytical technique for checking biodiesel blend. Portable ...

  • InfraSpec VFA-IR Spectrometer for Biodiesel Blend Measurements

    Synopsis: Simple, yet powerful, filter-based IR spectrometers are ideal for compliance to the new ASTM 7861 test method for accurately measuring biodiesel blend ratios. The Wilks InfraSpec analyzer was the instrument used to develop and validate this method and thus is the industry standard for field measurement of FAME (Fatty Acid Methyl Ester) blend percentages. ...

  • Microtox aquatic toxicity of petrodiesel and biodiesel blends: The role of biodiesel's autoxidation products

    The authors investigated the acute Microtox toxicity of the water accommodated fraction (WAF) of six commercial soybean biodiesel/petrodiesel blends at different oil loads. We analyzed five fatty acid methyl esters (FAMEs), C10–C24 n‐alkanes, four aromatics, methanol, and total organic carbon (TOC) content. At high oil loads, the WAFs' toxicity was significantly higher for blends containing ...

  • Get Comparable ASTM/EN Data for Biodiesel Blend Measurements While Saving Time and Money using Portable IR Analyzers

    Both EN 14078 and ASTM D7371 methods for measuring the percent biodiesel in diesel fuel use infrared analysis as the analytical method and are based around using an FTIR spectrometer which has the capability to do a multitude of analyses besides the biodiesel in diesel measurement. This is great for a laboratory where various biofuels measurements are required. However, if the only measurement ...

  • Putting the brakes on biodiesel

      Come December 31st, the Texas Commission on Environmental Quality (TCEQ) is set to effectively ban biodiesel in the state’s largest markets. The problem, they say, lies with the fuel’s nitrogen oxide (NOx) emissions and their contribution to the formation of ground-level ozone in Texas’ eastern counties. According to the TCEQ, biodiesel does not meet the stricter NOx standards recently ...

  • Portable IR analyzers: the ideal measurement solution for biofuels blend quality and wastewater testing

    Two challenges facing the biofuels industry involve compliance with blend quality standards and wastewater regulations. According to a study done by the National Renewable Energy Laboratory, 1 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 ...

  • Biodiesel Analysis with Mid Infrared - From Feedstock to Fuel

    Introduction The biofuels industry is growing rapidly and so is the need for analysis to ensure quality product. The parameters for quality biodiesel require different types of instruments and measurement systems, such as gas chromatographs (GC), titrators, centrifuges, infrared spectrometers... Although claims are out there for the analyzer that will do it all, unfortunately there is no one ...

  • Comparison of EN 14078 and ASTM D7371 infrared biodiesel methods

    Infrared (IR) analysis is the most widely used measurement technology for measuring biodiesel in diesel. Both EN 14078 and ASTM D7371 methods use infrared as the analytical method and more specifically FTIR (Fourier Transform Infrared) spectroscopy. Infrared is a common spectroscopic technique used for quantitative and qualitative analysis. In the biodiesel measurement, the fatty acid methyl ...

  • Simplified biofuels measurements with portable mid infrared analyzers

    Product quality begins at the production facility and extends to consumer filling station. Some process control or quality verification analyses can be done with quick and simple verification tests while others require more complete tests according to the ASTM or EN approved methods. Many crucial measurements can be performed by mid-infrared (IR) analysis. These measurements include free fatty ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...
