Rapid & Accurate Analysis Solutions for Sulphur & Chlorine in Biofuels

Biofuels are renewable fuels produced from feedstocks such as vegetable oil (palm oil, corn oil, rapeseed oil & soybean oil), animal fat, used cooking oil, biomass, or a blend of these. They are not produced from fossil fuels but rather from contemporary, human-induced processes. Biofuels are often used for blending with traditional fuels such as gasoil. However, it is also possible to use biofuels without blending them with traditional fuels. All biofuels - blended or not - must meet certain sulphur regulatory limits. In addition, some biofuels contain fairly high levels of chlorine which can cause corrosion damage during and after the production stages.

ENSURE ACCURATE RESULTS WITH XRF

X-ray Fluorescence (XRF) delivers rapid and accurate results for testing sulphur and chlorine in biofuels, backed by international standard test methods (ASTM, ISO, etc.). Advantages of XRF technology include its nondestructive nature, easy sample preparation process, and quick results, in addition to accuracy that is on par with alternative technologies like UVF (ultraviolet fluorescence). Having the correct sulphur value for biofuels is critical as they are typically blended with fuels that have a maximum specification of 10 mg/kg for sulphur (15 mg/kg in the US). This is important to note because oxygen absorbs XRF signals and as a result, can cause analysers to report falsely low sulphur and chlorine concentrations.

XOS’ Sindie® and Clora® XRF analysers deliver rapid and accurate results with exceptional reproducibility for both sulphur and chlorine in biofuels without the need for a matrix-matched calibration by simply applying a correction factor to the results. This allows professionals to certify their biofuel products more efficiently than with other methods.
