  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
