Abstract
Removal of residual water from a solvent-diluted bitumen is a challenging task because the water drops, in the emulsified form of a few micrometers, are extremely stable. A nontoxic and biodegradable polymer, ethylcellulose, was used to break up emulsified water from naphtha-diluted bitumen. It was found that the ethylcellulose polymer at 130 ppm dosage removed up to 90% of the emulsified water in the diluted bitumen by gravity settling after 1 h at 80 °C. The tests, extended to bitumen froth containing about 10% solids by weight, showed a 90% removal of the water in the diluted bitumen froth. The addition of ethylcellulose also assisted the removal of fine solids with the water. However, for bitumen froths containing 30% or more solids, the efficiency of water removal by ethylcellulose addition was found to be less effective. Micrographic images revealed that ethylcellulose broke up the water-in-bitumen emulsions by flocculation and coalescence.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
