Abstract

fetched live from OpenAlex

Solubility of carbon dioxide in n -octadecane and in three binary mixtures of n -octadecane and n -decane (0.25, 0.5, and 0.75 mol fractions of n -decane) has been measured at 323 K and at the pressures (1 to 6) MPa. Prior to phase equilibrium measurements, the density and viscosity of n -octadecane and of prepared binary mixtures were measured. Then, the phase behavior measurements were undertaken with an in-house designed PVT apparatus. The solubility of carbon dioxide in liquid hydrocarbons and its effect on the physical properties were examined. Increase in the pressure caused an increase in the carbon dioxide solubility and consequently, a decline in the viscosity of saturated liquid phase and an increase in the density of gas-expanded liquid were observed. The carbon dioxide solubility was lower in the heavier liquid mixture. The experimental data were well modeled with Soave–Redlich–Kwong and Peng–Robinson equations of state. Both equations of state have almost the same predictions for solubility while the Peng–Robinson equation of state is superior for density prediction.

Teacher imitation

Not 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.
