Area Of Science
- Environmental Science
- Analytical Chemistry
- Optical Engineering
Background
- Accurate measurement of emulsified crude oil thickness is vital for assessing offshore oil spill impacts.
- Conventional Laser-Induced Fluorescence (LIF) methods face limitations due to the complex nature of emulsified crude oil.
Purpose Of The Study
- To develop an enhanced method for accurately measuring emulsified crude oil thickness.
- To improve upon the limitations of traditional LIF techniques for oil spill assessment.
Main Methods
- A new device integrating LIF with visual imaging technology was developed.
- Two-Dimensional Convolutional Neural Networks (2DCNN) with attention mechanisms were used for image feature extraction.
- Partial Least Squares Regression (PLSR) was employed to correlate spectral and image data with oil thickness.
Main Results
- Emulsified crude oil exhibited distinct color features under 405 nm violet laser irradiation, correlating with thickness.
- Thickness estimation accuracy using image features was significantly higher than using spectral data alone.
- Validation with an unknown sample yielded a low average relative error of 0.759% for thickness measurement.
Conclusions
- The combined LIF and visual imaging approach offers a significant advancement in measuring emulsified crude oil thickness.
- This technology provides a more accurate and reliable tool for monitoring and managing offshore oil spills.
- Image feature analysis, particularly with 2DCNN, proved superior to spectral data for thickness determination.
