Ethylene Propylene Diene Monomer (EPDM) Membranes for the Pervaporation Separation of Aroma Compound from Water
Bibliographic record
Abstract
Ethylene propylene diene monomer (EPDM) rubber membranes were fabricated in thin-film composite form to separate an aroma compound, ethyl butyrate, from water and to study the effects of operating parameters on the pervaporation performance. A resistance-in-series model was applied to the pervaporation results to estimate the transport of the permeant. The partial flux of ethyl butyrate increased with the feed concentration. It was also found that the total flux decreased with increasing permeate pressure, whereas the organic flux increased. The effect of concentration polarization on the pervaporation performance was observed with changes in the feed flow rate. It was observed that the overall mass transfer coefficient was a function of the feed flow rate at fixed feed concentration.

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.
