Raman Systems for Olefins Monitoring
Olefins, a key component in gasoline blends, significantly influence fuel properties such as octane ratings and emissions performance. Accurately monitoring olefin concentrations during production is crucial for maintaining fuel quality and meeting regulatory standards. HORIBA's Raman spectroscopy technology provides an advanced solution for real-time, non-invasive analysis of olefins in gasoline, offering refiners unparalleled insight into blend composition and quality.

From oil and gas to pharmaceuticals and beyond, we provide reliable tools that empower you to monitor critical parameters, reduce operational costs, and improve product quality.
Olefin Determination
Raman spectra reveal distinct olefin peaks in the 1640–1680 cm⁻¹ region, allowing for precise differentiation between gasoline grades. For instance, a comparative analysis of regular and premium gasoline shows higher olefin concentrations in regular gasoline (12.6%) compared to premium gasoline (0.8%). This level of detail highlights Raman's capability to quantify key compositional differences directly in the process stream.
Olefins Model
Using partial least squares (PLS) regression models, Raman technology achieves exceptional accuracy in predicting olefin concentrations. A typical online PLS analysis demonstrates a strong correlation between Raman-predicted and laboratory-measured values, with a standard error of prediction of just 0.48% after removing outliers.
Olefins Model Validation
Validation of the PLS model on an independent dataset comprising 939 samples shows a similarly low standard error of prediction at 0.60% with only four outliers excluded.
Why HORIBA Process Raman for Olefins Monitoring?
Raman's ability to deliver this level of precision in real-time is a game-changer for refineries. By continuously monitoring olefins and other hydrocarbon components, operators can optimize blending processes, reduce costly off-spec production, and ensure compliance with stringent fuel quality requirements.
HORIBA’s Process Raman systems bring the power of molecular spectroscopy to gasoline production, enabling refiners to streamline operations while maintaining the highest standards of quality and efficiency. With real-time insights into olefin concentrations and other critical fuel parameters, HORIBA equips refineries with the tools needed to meet the demands of modern fuel production.
