Diesel Production Control – Combination of NMR and Simulated Distillation to Yield On-Line Carbon Number Distributions

by NMR, PAT, Process NMR

Process NMR Associates has developed a database of Simulated Distillation database on a large number of diesel fuels on our Shimadzu 2010-GC with SimDis Software. The analysis is being used to develop distillation prediction models for the process NMR systems as well as explore new avenues of control information that can be derived by combining carbon number distributions obtained from the GC data with the predictive capabilities of online NMR.

Simulated distillation allows carbon number distributions to be calculated and in combination with chemistry observed in the NMR analysis the effect of aromatics and olefins on the paraffin distributios can be estimated. Online NMR predictions can be established that yield real-time carbon number distributions for production control and sulfur species monitoring.

Extensive NMR Diesel Database Enhances NMR Model Performance for Unit Control and Product Manufacturing

by NMR, PAT, Process NMR

An extensive database (10 years) of diesel samples incorporating all refining processes (distillation through product blending) enables development of robust, wide ranging property predictions independent of crude sources and refinery processing. Consistent attention to data integrity enables expanding model ranges well beyond any typical single unit or process operation. The following slides elucidate the consistency in spectra whether obtained 10 years ago or last week, from within a refinery or on a laboratory spectrometer.

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 chemically closer to the hydrotreater constraint limit. The strength of NMR is that it quantitatively and accurately observesthe chemistry of each refinery stream and readily relates that chemistry to chemically dependent parameters such as distillation, cetane, freeze points, etc. The NPS strategy is to cut and control CDU diesel production as closely to the dibenzothiophene distillation limit as possible. Figure 1 illustrates this strategy in terms of both current and proposed NMR based measurements.
