Measurement of surface‐transfer coefficient values for CO<sub>2</sub> absorption in lime solutions in presence of surfactants
Bibliographic record
Abstract
Abstract A modified manometric apparatus has been used for the experimental determination of surface‐transfer coefficient values, used for the design calculations of various mass‐transfer equipments, for the absorption of carbon‐dioxide gas in saturated lime solution in presence of different types of surfactants. An analytical expression has been derived for estimation of the volume of gas absorbed, using the manometric data, for different times of absorption. The rate of gas absorption was found to remain constant initially for about 1 min and thereafter decreased with the progress of absorption time. Surface‐transfer coefficient values for gas absorption have been calculated using the experimental data of the volume of gas absorbed, without and with the addition of different concentrations of surfactants to the lime solutions. For a particular surfactant, surface‐transfer coefficient values were found to decrease with an increase in the concentration of surfactant in solution. The calculated values of the surface‐transfer coefficients for different surfactants are in close agreement with those reported in the literature.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
