Meeting Tier 3 Requirements with Ease and Precision
Meeting Tier 3 Requirements with Ease and Precision
16 May 2016Now that the U.S. Environmental Protection Agency (EPA) has enacted new, lower sulfur level requirement in gasoline (Tier 3), there is a renewed interest within the petroleum industry for measuring ultra-low level sulfur in fuels. In order to make the transition to lower maximum levels as smooth as possible, it is critical to seek out the most efficient and precise technologies for measuring sulfur at these new ultra-low levels. This application note demonstrates how monochromatic wavelength dispersive x-ray fluorescence (MWD XRF) can be used to measure sulfur down to 0.5ppm in samples from the petroleum industry.

X-Ray Diffraction and SpectroscopyX-Ray diffraction & spectroscopy are used in material characterization to discern the structure and elemental composition of a sample. X-Ray diffractometers (XRD) are superior instruments in elucidating the dimensional atomic structure of crystalline materials, including powders, thin films and single crystals. For large unit cells or ordered macromolecules, consider small-angle X-ray scattering (SAXS). X-ray spectroscopic techniques include X-ray fluorescence (XRF) and X-ray photoelectron spectroscopy (XPS), both providing simple and accurate methods for determining the elemental composition of a material. Energy dispersive (EDXRF) and wavelength dispersive (WDXRF) XRF spectrometers are available, as well as handheld/portable devices. High-resolution, 3D microstructure characterization of materials can be achieved with X-ray microscopes combining sub-micron resolution imaging with 3D computed tomography.

Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.PetroleumEPA MethodsEPA methods are procedures approved by the U.S. Environmental Protection Agency for monitoring and analyzing environmental pollutants, including air, water, and soil samples.
