Abstract
The mass-transfer performance of a spray column was tested experimentally for the removal of carbon dioxide (CO 2 ) from a gas stream by using an aqueous solution of monoethanolamine (MEA). The experiments were performed in absorption columns over ranges of process conditions. The performance of the spray was evaluated and presented in terms of the overall mass-transfer coefficient ( K G a e ). It was found that the performance of the spray column varies significantly with the tested process parameters, including gas flow rate, liquid flow rate, CO 2 partial pressure, MEA concentration, CO 2 loading, and size of spray nozzle. The results were further analyzed for the fundamental information on effective area ( a e ) and gas-phase mass-transfer coefficient ( k G ). The performance of the spray column was also compared to that of a packed column. The comparison demonstrates a great potential of using the spray column in the CO 2 capture application.

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 it
