Abstract

L'invention concerne un procédé et un appareil pour augmenter la proportion d'un gaz déterminé dans un mélange gazeux. Un ou plusieurs lits adsorbants fonctionnent suivant un cycle comprenant des étapes successives d'adsorption, de régénération sous vide et de remplissage. La pression régnant dans le ou les lits pendant le remplissage est détectée et ce dernier est interrompu lorsque cette pression atteint une valeur prédéterminée, et l'étape de régenération est réglée pour avoir une durée constante. Ledit procédé permet de maintenir un débit et une pureté du produit sensiblement constants malgré les variations de la capacité d'adsorption du ou des lits sous l'influence des températures variables. Application à l'isolement de l'air de départ d'un gaz riche en oxygène ou à la séparation d'un autre mélange gazeux.
