Zusammenfassung:	The Invention relates to a method of shutting down at least part of a gas scrub (G) and to a gas scrub (G) which comprises an absorber (A) and a regeneration part (R) and in which in normal operation a scrubbing medium (1) is circulated in a scrubbing medium circuit and thus laden in the absorber (A) at elevated pressure with substances removed from a gas mixture which are removed from the laden scrubbing medium (2) again in the regeneration part (R), wherein scrubbing medium (3) is removed from the scrubbing medium circuit, transferred into a storage tank (S) and stored there at atmospheric pressure. The invention is characterized in that laden scrubbing medium (3) is warmed (E1) and intermediately stored at elevated pressure in a degassing vessel (Z) in order to remove absorbed substances (5) from the scrubbing medium before it is passed into the storage tank (S).
