Kinetics of the Oxidative Degradation of Aqueous Monoethanolamine in a Flue Gas Treating Unit
Bibliographic record
Abstract
An investigation of the kinetics of the oxidative degradation of aqueous monoethanolamine (MEA) was conducted in a 300-mL autoclave in the temperature range 393−443 K and MEA concentration range 2−11 kmol/m 3 at 241−345 kPa O 2 pressure (i.e., O 2 concentration range). The results show that MEA oxidative degradation depends on both the O 2 and the initial MEA concentrations, as well as the temperature, according to the intrinsic kinetic model − r MEA = 2.5 × 10 5 e -(66 288.9/ RT ) [MEA][O 2 ] 1.5 . This work represents the first attempt at both obtaining intrinsic kinetic data for the oxidative degradation of MEA and formulating a kinetic model that fits the data based on the initial rate. The values obtained for the reaction orders for MEA and O 2 imply that oxidative degradation of MEA is more sensitive to increases in the O 2 concentration than in the MEA concentration. It also shows that, even though our experimental conditions enabled us to model the reaction as a homogeneous liquid-phase reaction, MEA oxidative degradation itself is not an elementary reaction.

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.
