Refiners can optimise their catalyst quality by measuring metals in crude, and then assess the payoff of those optimisations in real-time by measuring chlorine concentration trends in the catalysts themselves. UOP 979 is a well-accepted test method for determining the total chloride content of fresh, regenerated, and spent alumina-supported catalysts by WDXRF and EDXRF - provided the EDXRF instrument meets the precision criteria.

Read this whitepaper to learn about a reliable EDXRF solution to measure chlorine in catalyst while meeting the UOP 979 precision criteria.
