Standard Test Method for Vanadium and Nickel in Crude and Residual Oil by X-ray Spectrometry

Importancia y uso:

5.1 This test method provides a rapid and precise elemental measurement with simple sample preparation. Typical analysis times are approximately 4 min to 5 min per sample with a preparation time of approximately 1 min to 3 min per sample.

5.2 The quality of crude oil is related to the amount of sulfur present. Knowledge of the vanadium and nickel concentration is necessary for processing purposes as well as contractual agreements.

5.3 The presence of vanadium and nickel presents significant risks for contamination of the cracking catalysts in the refining process.

5.4 This test method provides a means of determining whether the vanadium and nickel content of crude meets the operational limits of the refinery and whether the metal content will have a deleterious effect on the refining process or when used as a fuel.
