  • 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 ...

  • 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 ...

  • 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. ...

  • 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 ...

  • Lower Resolution Infrared (IR) Spectroscopy Can Provide Higher Performance for Quantitative Biodiesel Measurements

    Resolution is often used as a yardstick of instrument performance in Infrared Spectroscopy.  This is especially true when the measurements are energy limited as they are in the mid-infrared.  For example, in both the European and ASTM standards - EN14078 and ASTM D7371 - for the determination of biodiesel in diesel fuel, a 4 cm-1 resolution is specified which is a relatively high ...

  • Evaluation of environmental impact and gaseous emissions of biodiesel fuels and blends of selected feed-stocks

    Thermal and gaseous emissions of biodiesel feed-stocks: sandbox tree, fluted pumpkin, black date and wild melon whose potentials as biodiesel fuels have been established in the earlier works of Igbum et al. (2012) were evaluated in order to ascertain and establish their environmental and emission impacts on the local and global environment. Effects of blending ratios on the thermal/gaseous ...

  • Empirical approach for the prediction of cetane number from the FAME composition

    Cetane number is a prime indicator in evaluating the quality of biodiesel fuel in the realm of diesel engines. Standards have been established world wide for cetane number determination, for example, ASTM D 613 in the USA, internationally, the International Organization for Standardization (ISO) standard ISO 5165, etc. These methods are usually arduous and expensive; the values obtained are ...

  • 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 ...

  • Fuel alternatives for heavy equipment

    High fuel prices are leading composters and wood grinders to reevaluate diesel-guzzling heavy equipment, looking to alternatives that are both more cost-efficient and environmentally friendly. This could be as “simple” as filling up existing machines with biodiesel blends, could involve swapping out a diesel model for an electric one, or even go as far as generating electricity on site to power ...

  • Cetane Number and Cetane Index

    This article summarises the findings of an Energy Institute (EI) sponsored Technical Development Project carried out by Cliff Lilley Consultancy, and outlines a review of the suitability of the current cetane index equation used in IP 380 Calculation of Cetane Index of middle distillates by the fourvariable equation (EN ISO 4264) (ASTM D 4737 procedure A**) for calculating Cetane Index (CI), to ...

  • Comparing TGA, FTIR and fixed filter infrared analyzers for measuring soot levels in in-service lubricants

    Measuring soot in diesel engine oil has become more important as soot levels get higher due to exhaust gas recirculation. As soot isone of the key indicators for the condition of the oil, diesel engine maintenance programs performing regular soot checks can realize cost savings by extending drain periods and reducing used oil disposal. TGA (Thermal Gravimetric Analysis) is the traditional method ...

  • 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 ...

  • Bio-Diesel- The alternate fuel for Indian Railways

    Global population explosion, rapid industrialization and greater human activities have been demanding more and more fuels/energy. On the other hand the reserve of fossil fuel is depleting day- by- day signaling a dark future for the mankind. In this scenario research in the field of renewable energy has increased. One such burning topic of the day is the production of “Bio-Diesel”. Bio-diesel is ...


  • United States Coast Guard (USCG) Implements Handheld Technology for Onboard Oil Testing in New Cutters - Case Study

    With a motto of “Always Ready,” the United States Coast Guard (USCG) has 11 missions specified by law including drug and migrant interdiction; ports, waterways and coastal security; fishery patrols; search and rescue; and national defense. The USCG’s newest ships include 22 Fast Response Cutters (FRCs) which recently entered service, and 36 more are currently on order. ...
