Rigorous Model for Predicting the Behavior of CO<sub>2</sub> Absorption into AMP in Packed-Bed Absorption Columns
Bibliographic record
Abstract
A rigorous computer model was developed for the simulation of the absorption of CO 2 in aqueous 2-amino-2-methyl-1-propanol (AMP) solutions in a packed absorption column that takes into account the heat effects. This model predicts the concentration and the temperature profiles along the packed column for the CO 2 −AMP system. These profiles were compared with the experimental data that were obtained from two pilot-plant studies. The first study was with a column packed with 12.7-mm Berl Saddles, and the second study was with a high-efficiency structured packed absorber. The predicted results were found to be in close agreement with the measured values. For the experimental data from University of British Columbia, the average absolute deviations between the predicted and measured data in terms of concentration and temperature profiles are 9.7% and 2.3%, respectively. For the experimental data from University of Regina, the average absolute deviation between the predicted and measured concentration profiles is 13.8%. The model predictions could be improved by using more accurate physicochemical properties, when available.

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.
