Abstract

fetched live from OpenAlex

Abstract Les performances de l'étape d'extraction du procédé de purification de l'acide phosphorique de voie humide par extraction liquide—liquide avec la méthyl isobutyl cétone ont été déterminées en faisant appel à la méthodologie des plans d'expériences. Pour ce faire, un plan factoriel complet 2 4 avec comme variables, la concentration de l'acide d'alimentation, le taux de solvant, la température et le nombre d'étages théoriques d'extraction a été réalisé. Les modèles obtenus ont permis de prédire les performances de l'extraction en terme aussi bien de rendement en P 2 O 5 que de facteur de décontamination de l'acide produit et ce quelle que soit la teneur en eau du solvant recyclé. Le recours à la fonction désirabilité a permis de déterminer l'optimum multiréponse réalisant le meilleur compromis entre aussi bien un rendement en P 2 O 5 de l'extraction élevé que des facteurs de décontamination de l'acide désextrait acceptables.

Full frame distilled prediction

Teacher imitation

Not 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.
