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).

Abstract: Disclosed is a process for the regeneration of an adsorber (A1). The adsorber (A1) is regenerated by contact with a gaseous stream (S2) and the outflow of the adsorber (A1) comprising condensate of stream (S2) and organic composition (OC1) collected in a device. After regeneration of the adsorber (A1) the stream (S2) in the adsorber (A1) is replaced completely or at least partially by the content of the device. Then the adsorber (A1) is fed with organic composition comprising at least one olefin, at least one alkane and at least one compound containing oxygen and/or sulfur.
