ABSTRACT:
A moist hydrogen stream is dried by cooling to below the dewpoint of water and separating water, drying further over a regenerable solid absorbent, separating a part stream of dried gas and using it to regenerate water-loaded absorbent, and recycling the resulting moist regeneration gas stream into the moist hydrogen stream upstream of the water separation step. If the starting moist hydrogen stream is produced by shift, CO.sub.2 -removal and methanation the recycled gas is preferably introduced between CO.sub.2 removal and methanation. If it is produced from unreacted methanol synthesis gas the recycled gas is preferably introduced upstream of methanol synthesis.
