Abstract Information :

Elements such as Sulfur, Nickel, Vanadium and Iron are known to rapidly deactivate catalysts in the refinery and are therefore part of daily measurement schemes for crude oils, marine fuels, gas oils and intermediate streams such as VGO. Common laboratory practice for these analyses is the use of Inductively Coupled Plasma Mass Spectroscopy (ICP), which typically requires time consuming and intensive sample preparation procedures. With the ever increasing need to save time and increase throughput, high definition XRF (HDXRF) may be used in petroleum labs as a fast and accurate screening method for metals like Iron, Nickel and Vanadium. As we will show in the following study, accurate results can be obtained with HDXRF for difficult samples such as wet crudes, VGO and Catalyst powders, offering petroleum labs the ability to work more efficiently in certifying their products.
