Abstract

The invention relates to a process for regeneration of an adsorber (A) by contact with a stream (S1), wherein the stream (S1) is heated in advance by at least two heat exchange units (HEU1) and (HEU2). As outflow of the adsorber (A) a stream (S2) is obtained, which is passed through at least two heat exchange units (HEU1) and (HEU2) traversed by stream (S1), wherein the temperature of stream (S2) fed into each heat exchange unit is higher than the temperature of stream (S1) fed into the heat exchange units (HEU1) and (HEU2), in order to directly transfer heat from stream (S2) to stream (S1).
