Abstract

L'invention concerne des dispositifs de fractionnement de mélange gazeux par variations alternés de pression. Une égalisation des pressions entre les lits adsorbants A et B est réalisée par leurs extrémités d'alimentation 18 et 26. Il existe un réservoir 84 destiné à stocker du gaz purifié qui sera réintroduit dans la sortie 66 du produit en cas de besoin, soit pour régulariser le débit de sortie, soit pour compenser une défaillance du dispositif ou de l'alimentation électrique. Le dispositif permet d'utiliser un compresseur de plus faible puissance et assure la production d'un gaz de plus grande pureté à un débit plus uniforme.The invention relates to devices for fractionating a gas mixture by alternating pressure variations. Pressure equalization between the adsorbent beds A and B is achieved by their supply ends 18 and 26. There is a reservoir 84 intended to store the purified gas which will be reintroduced into the outlet 66 of the product if necessary, either for regulate the output flow, either to compensate for a failure of the device or the power supply. The device allows the use of a lower power compressor and ensures the production of higher purity gas at a more uniform rate.
