A cross‐flow rotating packed bed toward desulphurization of marine exhaust gas
Bibliographic record
Abstract
Abstract The marine exhaust gas containing SO 2 leads to serious impacts on human health and marine environments. Due to the strict emission standard of marine exhaust gas and the limited space of ships, desulphurization process intensification is urgent. Herein, a cross‐flow rotating packed bed (CF‐RPB) with a compact size was developed toward desulphurization of marine exhaust gas. According to the emission standards of different sea areas, the characteristics of simulated open seawater desulphurization (OSD) and closed alkali desulphurization (CAD) were systematically evaluated. The respective correlations for K y a of OSD and CAD were proposed to predict the height of CF‐RPB. The desulphurization efficiencies of 86% in the OSD and 97% in the CAD were achieved in a three‐stage CF‐RPB, satisfying the emission standard. Compared with the traditional spray tower, the CF‐RPB has a higher mass transfer coefficient with a smaller volume, which has great potential for desulphurization of marine exhaust gas.

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.
