Abstract: Method for drying a gas which has been compressed by a compressor (1) wherein compressed gas (2) from the compressor is driven through an amount of drying agent (3) until a dried, compressed gas (4) is obtained. An amount of used drying agent (7) is regenerated by driving a part (5) of dried compressed gas (4), which is heated first by the compression heat of compressor (1), through used drying agent (7). Moisture is absorbed from used drying agent (7) by a part (5) of the dried compressed gas (4), which is then condensed and separated by cooling. Part (5) of dried compressed gas (4) is then mixed with compressed gas (2) from the compressor to be dried.
