Abstract

Procédé d'ajustement de la production d'oxygène produit par un procédé d'adsorption de type (V)PSA au moyen d'une unité comportant X adsorbeurs avec X supérieur à 2 suivant chacun en décalage un cycle nominal de pression de durée Tnominal, comprenant au moins les étapes de production, décompression, purge et recompression et fournissant une production nominale d'oxygène P, comprenant les étapes successives suivantes : a) détermination de la production souhaitée P' par rapport à la production nominale P, avec P' s'exprimant en pourcentage de la production nominale P b) détermination simultanée du temps mort Tmort nécessaire pendant lequel au moins un adsorbeur doit être isolé pour atteindre la baisse de production souhaitée et de l'entier N indiquant l'application de ce temps mort un temps de phase sur N, de manière à ce que la formule suivante soit respectée: Tmort=Tphase * N * [1/P'-1] Avec : - Tphase = TnominaI/X - N est un nombre entier supérieur ou égal à 6 et est choisi de façon à minimiser la durée Tmort tout en respectant Tmort ≥ Tmort_minimum -Tmort_minimum > 1s.
