Hyperspectral Imaging for Improved Process Monitoring and Control of Bitumen Production

This project addresses technology gaps in improving bitumen production performance, by establishing the proof of concept of using hyperspectral imaging for ore classification, and assessing its potential impact on the observability of batch, laboratory-scale, water-based extraction processes.

This project aims to determine hyperspectral feature sets, classification schemes and predictive models to discriminate samples with processibility issues. It examines the trade off of implementing these tools with instrumentation collecting broadband data. This would build on previous work which has established that this approach can predict bitumen content and < 2micrometre fines content.

Figure 1: Reflectance spectra of oilsand converted to wavelet representation for two samples (1L07 and SUN6). A number of oil (O), clay (C), and water (W) features controlling predictive models (e.g Figure 3) are identified.

Figure 2: Broadband spectral predictive model of % total bitumen content (TBC). Circles: modeling data suite, Stars: Validation data suite. The models were derived from the analysis of hyperspectral data to optimized the selection of feature sets.
