Improvement of the Spray Column Performance for CO<sub>2</sub> Capture in an Amine Absorption Process Using Multiple Nozzle Arrangement
Bibliographic record
Abstract
The only commercially viable technology available today for CO 2 capture on an industrial scale is the amine absorption process. However, the capture cost is still significantly high and needs to be reduced to encourage more industries and businesses to implement the technology. One aspect of the process with a major scope of improvement is the absorber column. This research investigated the use of a spray column for gas–liquid contacting operation as compared to the currently used packed bed absorber, which is associated with high capital and maintenance cost. An experimental investigation was carried out using 30 wt % monoethanol amine as the solvent to obtain a CO 2 concentration and temperature profile along the spray column length and measure the overall absorption efficiency. The multinozzle arrangement used in this study showed the best performance as compared to the single-nozzle spray column with an increase in absorption efficiency by up to 10% under similar operating conditions.

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.
