The invention provides for chiller a regeneration gas to the same temperature as the feed gas. This prevents upsets in a downstream cryogenic fractionation unit. In one embodiment, the gas is first treated in a in a solvent absorbent bed, cooled and then further treated in a molecular sieve adsorbent bed. La présente invention consiste à fournir à un compresseur frigorifique un gaz de régénération à la même température que celle du gaz d'alimentation. Ceci empêche des refoulements dans une unité de fractionnement cryogénique en aval. Dans un mode de réalisation, le gaz est tout d'abord traité dans un lit absorbant de solvant, est ensuite refroidi, puis le traitement se poursuit dans un lit adsorbant à tamis moléculaire.
