Determination of the vanadium content of hydrotreated petroleum residues by visible spectrometry

The spectrometric method for the determination of V in heavy petroleum fractions has been extended to hydrotreated residues. The V content of a hydrotreated residue can be determined from its visible light absorbance at 550 nm. The simplicity and accuracy of this method make it suitable for process...

Description
Summary:The spectrometric method for the determination of V in heavy petroleum fractions has been extended to hydrotreated residues. The V content of a hydrotreated residue can be determined from its visible light absorbance at 550 nm. The simplicity and accuracy of this method make it suitable for process control applications although a specific correlation must be developed for each feedstock. Absorbance measurements performed on dissolved and undissolved residues prove that the correlation is not distorted by interactions with the solvent.--AA
