Process for regenerating a laden scrubbing medium from a gas scrubbing for purification of raw synthesis gas, wherein the raw synthesis gas comprises at least carbon monoxide, hydrogen (H 2), carbon dioxide (CO 2) and hydrogen sulfide (H 2 S), in which the laden scrubbing medium is at least partially freed of bound gas constituents in a regeneration stage, to obtain a regenerated scrubbing medium, wherein the laden scrubbing medium is regenerated by stripping with scrubbing medium vapour in the regeneration stage and wherein the gas scrubbing is a physical gas scrubbing and the scrubbing medium comprises methanol as the main constituent, wherein the proportion of methanol in the scrubbing medium comprises at least 75% by weight, wherein after withdrawal from the regeneration stage the regenerated scrubbing medium is supplied to an intermediate vessel and the regenerated scrubbing medium is withdrawn from the intermediate vessel and supplied to an absorption apparatus for purifying raw synthesis gas and laden scrubbing medium is withdrawn from the absorption apparatus and subsequently supplied to a decompression stage to obtain laden scrubbing medium having a reduced concentration of bound gas constituents which is withdrawn from the decompression stage and supplied to the regeneration stage and scrubbing medium withdrawn from the decompression stage is supplied to a reabsorber before it is supplied to the regeneration stage, wherein CO 2 is stripped out of the laden scrubbing medium by an inert gas in the reabsorber and any H 2 S unintentionally co-stripped in the reabsorber is reabsorbed by laden methanol withdrawn from the decompression stage and supplied to the reabsorber. the raw synthesis gas comprises at least carbon monoxide, hydrogen (H 2), carbon dioxide (CO 2) and hydrogen sulfide (H 2 S), in which the laden scrubbing medium is at least partially freed of bound gas constituents in a regeneration stage, to obtain a regenerated scrubbing medium, wherein the laden scrubbing medium is regenerated by stripping with scrubbing medium vapour in the regeneration stage and wherein the gas scrubbing is a physical gas scrubbing and the scrubbing medium comprises methanol as the main constituent, wherein the proportion of methanol in the scrubbing medium comprises at least 75% by weight, wherein after withdrawal from the regeneration stage the regenerated scrubbing medium is supplied to an intermediate vessel and the regenerated scrubbing medium is withdrawn from the intermediate vessel and supplied to an absorption apparatus for purifying raw synthesis gas and laden scrubbing medium is withdrawn from the absorption apparatus and subsequently supplied to a decompression stage to obtain laden scrubbing medium having a reduced concentration of bound gas constituents which is withdrawn from the decompression stage and supplied to the regeneration stage and scrubbing medium withdrawn from the decompression stage is supplied to a reabsorber before it is supplied to the regeneration stage, wherein CO 2 is stripped out of the laden scrubbing medium by an inert gas in the reabsorber and any H 2 S unintentionally co-stripped in the reabsorber is reabsorbed by laden methanol withdrawn from the decompression stage and supplied to the reabsorber.
