Process NMR Application: Spectro-Molecular Control for Enhanced Diesel Recovery

NMR Process Systems - Integrated Solution Application for Crude Unit and Downstream Processes: Spectro-Molecular Control for Enhanced Diesel Recovery NMR Process Systems (NPS) on-line NMR based analytical and process control strategy for enhanced diesel recovery at the crude distillation unit maximizes clean diesel recovery by enabling closer cut point control in the mid-section of the CDU. Clean Fuels regulations in both the European and American markets have had a substantial impact on a refiners ability to maximize product draws at the refinery front end. Extremely low sulfur requirements for gasoline and diesel have resulted in refiners now being more constrained at the hydro-treaters. Lack of reliable, focused, measurement and control of critical CDU product draws has forced many refiners to significantly undercut these draws in order to ensure minimum error in the final product blends, especially with respect to total sulfur. Depending on a refinery's crude supply and CDU capacity, a conservative estimate of 300-500+ barrels per day of loss diesel production is typical. With an average of $25-$35 per barrel margin loss, the economic impact of these Clean Fuels Regulations are substantial. Integrating proven NMR technology with a focused measurement and control strategy enables crude unit operations to cut…
