Online Analysis of Sulfur in Diesel line by a Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry

摘要

This paper proposes the application of a monochromatic wavelength dispersive X-ray fluorescence (MWDXRF) technique developed in the X-ray Optical Systems laboratory Inc. The technique measures low-level sulfur (uls) in fuel. Data for ultra low sulfur in diesel were collected and analyzed using the combination of the mentioned technique and the usage of engineering tools as a fastloop array and a measurement technique. This provides a qualitative method for Diesel sulfur analysis of the Refinery Ing. Antonio M Amor (RIAMA) in Salamanca, Guanajuato. The pooled limit of quantification (PLOQ) for ultra-low-sulfur diesel was found to be less than 1.5 ppm in this study. The reproducibility of 15-ppm sulfur diesel fuel was determined to be better than 3 ppm (95 % confident level). This work shows the performance of the production of Diesel with less than 15-ppm in sulfur lines in the Hydrodesulfurizer Unit of Diesel (HDD) of the refinery. Results and conclusions discusses the better and cheaper method for the production of ultra low sulfur Diesel in the refinery .
