Abstract:
The determination and analysis of the content of crude oils and and other petroleum products is an integral part of the refinement process, ensuring that the metal content of the crude oil is at an acceptable level. If the presence of certain metals in the crude oil is too high, it can create imperfections during the refining process. Additionally, it is imperative to monitor the chlorine content, as the presence of chlorine can lead to corrosion if it goes unchecked through refinement. The EDXRF Elemental Analyzer is equipped to make these determinations rapidly and with a great deal of qualitative detail and quantitative accuracy. The instrument is capable of determining the total sulfur content and total lead content in petroleum products, such as diesel fuel, jet fuel, kerosene, other distillate oil, naphtha, residual oil, lubricating base oil, hydraulic oil, crude oil, unleaded gasoline, and gasohol. The EDXRF features a high performance silicon drift semiconductor detector, peltier electronic cooling, and an optimum balance of spectral resolution and high count rate. Due to the EDXRF’s speed and precision, it can be used repeatedly at multiple points before refinement in order to ensure the most desirable content of crude oil. In addition to gathering such measurements, the EDXRF is fitted with a suite of software that enables thorough analysis of data.
