As of January 1, 2015, regulations for marine fuels have become more stringent. Ships in designated emission control areas are restricted to using fuel oils with a maximum sulfur content of 0.1%. Outside emission control areas, the current limit for sulfur content in fuel oil is 3.5% but this is expected to fall to 0.5% in the near future. Ships taking on fuel oil for onboard use need a bunker delivery note, stating sulfur content of the supplied fuel. With thousands of vessels worldwide, the demand for low-sulfur marine diesel/fuel is expected to increase drastically.
The X-ray fluorescence (XRF) technology is the most suitable method for total sulfur analysis in petroleum products, meeting several ASTM standards (D4294 and D7212). The Hobré Metorex C100 EDXRF analyzer is the ultimate robust tool for on-line measurement of total sulfur in liquid petroleum products. The analyzer is not limited by the final boiling point and is capable of measuring a wide range of sulfur concentrations, from 1 ppm to percentage levels.
We have installed hundreds of Metorex process sulfur analyzers worldwide, and have over 25 years of industry experience, providing proven solutions for online analysis, including sample conditioning, flushing systems and sample recovery systems.
