An absorber (1) comprises a shell (2), wet tubes (3) and cooling fluid supply (4a) and collection portions (8a). Partition walls (2a,2b,2c.2d) divide the shell (2) into at least three zones. The wet tubes (3) are disposed parallelly in the shell (2), passing through the partition walls (2a,2b,2c,2d). The cooling fluid supply portion (4a) communicates with the open end of the wet tube (3) to supply a cooling fluid thereto. The cooling fluid collection portion communicates with the other open end of the wet tube to collect the cooling fluid in the wet tube (3) and discharge it outside. A gap (9) is formed between the wet tube (3) and the partition walls (2b,2c) facing the intermediate zone (6). The liquid working fluid is supplied to the uppermost zone (5) so as to flow down from the gap (9) to the zone (7) located below the intermediate zone and is discharged outside. The gaseous working fluid is supplied to the intermediate zone (6) so as to come into contact with the liquid working fluid flowing on the outer peripheral surfaces of the wet tubes (3). <IMAGE>
