Abstract:
The use of Raman spectroscopy for analysis of the various refinery products has increased dramatically in the last 20 years. While ASTM Laboratory tests are still needed and are the gold standard in order to build such models, the need to constantly run them is less. This advantage can be expanded to the online monitoring of products such as Naphtha where this fraction is a key component of the gasoline blending process and/or feed of other units within the refinery. Naphtha can be consistently separated into two fractions, light and heavy. Ranging from C5/C7 for the light cut and up to C9 for heavy. Regardless of the Naphtha process, Raman spectroscopy can be an important tool to verify the unit targets and provide tight control off key properties. It is also used extensively for distillates such as Jet and Diesel. Throughout this presentation examples will be shown of the analysis Raman can be implemented for, with the aid of regression and classification type models along with corresponding laboratory test data. Examples of the instrumentation used in refinery settings along with feedback from active users will also be provided. Raman has allowed unit operators to monitor and control their blends more effectively without having to invest in multiple individual property analyzers.
