Patent ID: 7517390

Claim:
A process for regenerating adsorbers in an adsorber station (A), which is used to purify a synthesis gas ( 3 ) flowing to a cryogenic gas separation unit (Z) of a synthesis gas installation, in which an oxo gas product ( 12 ) or a methanol synthesis gas ( 14 ) is obtained from said cryogenic gas separation unit ( 2 ), wherein a part-stream ( 5 ) is removed from the purified synthesis gas stream ( 4 ) downstream of an adsorber station (A) but upstream of said cryogenic gas separation unit (Z), and said part-stream ( 5 ) is returned to the adsorber station (A) as regeneration gas for regenerating the adsorbers, characterized in that the part-stream of synthesis gas ( 6 ) used as regeneration gas, after having passed through the adsorber(s) to be regenerated, is admixed with the oxo gas product ( 12 ) or the methanol synthesis gas ( 14 ).
