Abstract
This work has extended the knowledge of corrosion inhibition by sodium metavanadate (NaVO3) and copper carbonate (CuCO3) in the carbon dioxide (CO2) separation process using aqueous solutions of monoethanolamine (MEA). The inhibition behavior and performance of these two inhibitors were examined using the electrochemical polarization technique in a 5-kmol/m3 MEA saturated with CO2 at 80°C. The results showed that NaVO3 generally offered superior inhibition performance over CuCO3. The performance of both inhibitors deteriorated when the heat-stable amine salt represented by oxalate was present in the solution. The CuCO3 was found to induce some pitting tendency but NaVO3 did not.

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 it
