Raman Systems for Octane Giveaway Reduction

• Accuracy and Precision: Raman-based octane models provide full-range measurements across all seasonal blends with a precision of 0.1 to 0.2 octane units, consistently meeting or exceeding ASTM guidelines.
• Crude Slate Flexibility: Unlike NIR, Raman spectroscopy is unaffected by crude slate changes, eliminating the need for unique models for different crudes. This flexibility streamlines operations and reduces the complexity of blend monitoring.
• Narrow and Discrete Peaks: Raman spectra feature sharp, non-overlapping peaks, unlike the broad, overlapping signals seen in NIR. This results in more robust and interpretable models.
• Efficient Calibration: Raman models typically require fewer calibration samples, producing robust, long-lasting models with improved standard errors of prediction.

HORIBA’s Process Raman technology also enables modular modeling, allowing full-range octane models to be easily divided into sub-models tailored to specific seasonal or geographical blend requirements. This adaptability ensures consistent accuracy and compliance across varying fuel specifications.

By improving blend performance, reducing reprocessing needs, and minimizing tankage requirements, HORIBA Process Raman helps refineries achieve a measurable reduction in octane giveaway. This translates to lower production costs, optimized resource utilization, and enhanced profitability—all while maintaining the highest standards of fuel quality and compliance.
