Experimental and modelling studies of MacKay River bitumen and light <i>n</i>‐alkane binaries
Bibliographic record
Abstract
Abstract Solubility of light n ‐alkanes in bitumen as well as density and viscosity of the bitumen‐rich phase are the necessary data for simulation and study of the solvent‐aided thermal recovery processes of bitumen. This paper presents experimental data for MacKay River bitumen with n ‐alkane solvents (methane, ethane, propane, and butane). The viscosity and density of the solvent saturated bitumen phase are measured to determine the effect of solvent dissolution on the thermo‐physical properties of bitumen. The solvent‐bitumen system is modelled using the Peng‐Robinson equation of state (PR‐EoS). Moreover, experimental viscosity and density data of solvent‐saturated bitumen are correlated. The effective density and viscosity of the dissolved solvent molecules are obtained using the experimental density and viscosity data for the bitumen‐solvent system.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
