with a phosphorus-free, sulphur-free, metal-free dispersant demonstrates synergistic performance characteristics while utilising about 50% less phospho- rus concentration. This patent-pending technology offers superior iron phos- phate dispersancy from a process and downstream fouling perspective compared to conventional phosphate- based and dispersant-based formulations. This optimised composition has been developed into a commercial product line marketed under the Predator name and is currently under- going field trials at multiple refineries around the world. The integration of the Predator High-Temperature Corrosion Assessment methodology, coupled with this new low-P multi- functional corrosion treatment chem- istry, presents a viable solution for the processing of high-acid crudes and their blends with increased reliability, profitability, and sustainability. *Predator is a trademark of Veolia Water Technologies and Solutions; may be regis- tered in one or more countries.
