Simultaneous determination of sulfur and chlorine in crude

Monitoring the sulfur and chlorine content is important in crude. In crude oil, chlorine may be present through natural processes or possible adulteration. If unmeasured or not corrected for, chlorine may bias the sulfur measurement and potentially cause corrosion damage in blending operation, in pipelines or during the refining process. The industry requires a fast, simple means of screening and monitoring the chlorine content of crude at the well site, along pipelines, during blending and other pre-refining checks.

Rigaku NEX CG _PETROLEUM, employing monochromatic polarized excitation, brings the industry a simple means to simultaneously measure sulfur and chlorine from one pour in 300 seconds. The NEX CG delivers the lowest chlorine detection limits available with EDXRF spectroscopy. Please request AppNote #1432 for more details.

Sulfur in ULSD by ASTM D7220-12

Regulations around the world have limited the amount of sulfur in various fuels oils with particular attention to diesel fuel. Regulations limiting sulfur concentration effects all levels of the petroleum industry around the world, from the price of crude oil, to blending and refining, pipelines, transportation and storage, as well as product QC at the refinery level and as fuel is delivered to the pump.

Rigaku NEX CG _PETROLEUM provides a fast, reliable method of measuring and monitoring ultra-low sulfur concentrations in diesel and other petroleum products. A typical empirical calibration, shown at right as an example, was built using a suite of seven certified diesel calibration standards. For a 300 second analysis time, the lower limit of detection (LLD or LOD) is 0.54 parts-per-million (ppm). Please request AppNote #1024 for more details.
