Optimizing crude desalters to ensure optimum FCCU and DCU performance

Conference: Rotterdam 2019

To improve margins, refiners continuously look to optimize feedstock blends. Variability can bring significant operational challenges during the refining process that must be overcome. One critical need is the efficient removal of solids, salts, and water from the crude feedstock. This has become increasingly difficult when processing certain opportunity crudes that can have all of these detrimental properties at high levels. These contaminate can have a significant impact on downstream refinery units such as the FCCU and DCU.

Tracerco offers unique online and non-intrusive measurement and diagnostic technologies to assist operators with modification and optimization projects, enabling maximized production efficiency with minimum cost impact. In this paper the use of radioisotope technology to optimize the performance of desalters will be explored and how optimization of the upstream desalter can minimize effects on the downstream process plant.
