Abstract

Procédé de séparation d'un mélange de gaz au sein d'un ou plusieurs étages D1 , D2 ... Dn de diffusion, dans lequel chaque étage est alimenté à un débit optimal grâce à une régulation E, G1 , G2 ... Gn , compte tenu de la concentration de la charge a en gaz le plus léger et du débit diffusé de ce gaz, tel que la totalité de ce dernier gaz passe dans la phase diffusée. Grâce à son rendement amélioré, ce procédé est compétitif avec d'autres procédés de séparation de gaz, tels que les procédés cryogéniques.Process for separating a gas mixture within one or more diffusion stages D1, D2 ... Dn, in which each stage is supplied at an optimum flow rate thanks to a regulation E, G1, G2 ... Gn , taking into account the concentration of the load a in the lightest gas and the diffused flow rate of this gas, such that all of the latter gas passes into the diffused phase. Thanks to its improved efficiency, this process is competitive with other gas separation processes, such as cryogenic processes.
