Abstract

L'invention concerne un système (3) de contrôle d'un débit d'argon d'un fluide (120) en sortie d'un ensemble (1) d'au moins une colonne de distillation pour atteindre un taux de dioxygène cible (SP). Le système comprend : - un capteur (9) agencé pour mesurer un taux de dioxygène (PV) dans un fluide comprenant de l'argon en sortie de l'ensemble d'au moins une colonne de distillation, - un régulateur (11) agencé pour déterminer une variation (Δregul) de débit d'argon requise en fonction de la différence entre le taux de dioxygène mesuré par le capteur et un taux de dioxygène cible, - un contrôleur (13) agencé pour générer un signal de commande relatif à un débit d'argon visé, ledit débit d'argon visé étant déterminé en fonction de la variation de débit d'argon requise déterminée par le régulateur et de variations du taux de dioxygène mesuré par le capteur, - une vanne (15), pilotée par ledit contrôleur, agencée pour modifier le débit d'argon du fluide en sortie de l'ensemble d'au moins une colonne de distillation pour obtenir le débit d'argon visé.
