Solvent Extraction of Degradation Products in Amine Absorption Solution for CO2 Capture in Flue Gases from Coal Combustion: Effect of Amines
Bibliographic record
Abstract
Formate degradation product was extracted in monoethanolamine (MEA), N-methyldiethanolamine (MDEA), 2-amino-2-methylpropan-1-ol (AMP) and their blend by OH-aliquat336 in 2-ethyl-1-hexanol. The results showed that the extracted formate decreased with an increase of amine concentration due to the increase of interaction of the amine with formate. The blended amine (3 M MEA+1 M MDEA+1 M AMP) had higher extraction efficiency than single 5 M MEA. Extraction efficiency was increased with an increase of temperature. In the presence of CO2 loading, the extraction efficiency of formate decreased due to competitive reactions between carbamate (R1R2NCOO−), bicarbonate (HCO3−) and carbonate (CO32−) with the extractant.

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.
