Abstract
The liquid in the vat portion of the hydrogen withdrawing column is sub-cooled, expanded and divided into three flows: a first flow which is sent directly at about its bulb temperature into the column for separating CO and CH.sub.4, a second flow which is vaporized and warmed up to its dew point and is introduced at that temperature into the separation column and a third flow which is vaporized and warmed to a temperature which is intermediate between said bulb and dew temperatures and which is introduced into the separation column at that intermediate temperature. Application to the production of carbon monoxide and methane from a gas for reforming hydrocarbons.
