Abstract

Dispositif de purification d'un mélange gazeux comprenant deux colonnes (13, 14, 15) d'adsorbant raccordées en parallèles à une source (S) de gaz sous pression via un circuit (16) via un dispositif de régulation (100) de débit comprenant une conduite (2) de transfert munie d'une extrémité (12) amont reliée à la source (S) et une extrémité (22) aval reliée à la colonne (13, 14, 15) et une première (3) et une seconde (4) vannes disposées en série, le dispositif (100) de régulation de débit comprenant une conduite (10) de dérivation de la première (3) vanne, ladite, la première vanne (3) étant sensible au différentiel entre les extrémités amont (12) et aval (22) de la conduite (2) de transfert et étant conformée pour passer de l'état fermé à l'état ouvert uniquement lorsque le différentiel de pression entre l'extrémité (12) amont (22) et l'extrémité aval est inférieur à un seuil déterminé, de sorte que tant que le différentiel de pression entre l'extrémité (12) amont et l'extrémité (22) aval est supérieur audit seuil, le transfert de fluide de l'extrémité amont (12) vers l'extrémité aval est possible uniquement lorsque la seconde vanne (4) ouverte et via l'organe (11) de limitation de débit de la conduite (10) de dérivation.
