Area of Science:

  • Analytical Chemistry
  • Petroleum Geochemistry

Background:

  • Crude oil characterization is crucial for exploration and refining.
  • Fluorescence spectroscopy offers a sensitive method for analyzing organic compounds.

Purpose of the Study:

  • To develop predictive models for crude oil API gravity and aromatic concentration using fluorescence lifetimes.
  • To investigate the correlation between fluorescence lifetimes and oil properties.

Main Methods:

  • Measurement of average fluorescence lifetimes for nine North Sea crude oils using pulsed LED excitation (460 and 510 nm).
  • Analysis of fluorescence lifetimes across a range of emission wavelengths.
  • Application of partial least-squares (PLS) methods for model generation.

Main Results:

  • Fluorescence lifetimes ranged from 1.8 to 8.2 ns.
  • Linear correlation observed between average lifetimes, API gravity, and aromatic concentration.
  • Predictive models achieved accuracies of +/- 7.6 API degrees for gravity and +/- 5.4% for aromatic concentration.

Conclusions:

  • Fluorescence lifetime measurements provide a viable method for quantitative analysis of crude oil properties.
  • The 460 nm excitation source yielded optimal results for predictive modeling.
  • Ratio of fluorescence lifetimes at specific wavelengths improved aromatic concentration prediction.
