Measurement of sulphur in oil and fuels for oil & gas industry - Oil, Gas & Refineries

There is a continuing and increasing demand for a rapid, simple and cost-effective measurement of sulfur in a wide range of petroleum products including automotive, marine and aviation fuels. Benchtop EDXRF instruments such as the world renown Lab-X3500 and associated X-Supreme8000, can be found in many refinery laboratories/testing houses, with the instrument often operated by production staff on a 24/7 basis, giving accurate results conforming to globally accepted test methods, e.g. ASTM D4294, ISO20847, and the new ISO13032,etc. Both instruments used the analytical technique of Energy-Dispersive X-ray fluorescence (EDXRF) which is well regarded for its excellent performance, versatility, ease of use, speed, and cost-effectiveness.

At present there are two main types of sulfur analysis in petroleum products:

  • Ultra low sulfur, often called zero sulfur fuel, with concentration levels at or below 10mg/kg, (or 15mg/kg in the USA)
  • Higher sulfur concentration values from 50mg/kg to 5%.

Within the oil supply system from shipment of crude oil to refining, distribution, storage and subsequent use in automobiles, aboard ships etc, quality control/assurance is required at almost every stage of the process. The Lab-X3500 and X-Supreme8000 are field proven instruments that can measure sulfur from a few ppm to high % covering all analytical requirements.
