Abstract

Method whereby a gas is first compressed by a multistage compressor (1) and then dried by a pressure swing adsorber (50). The pressure swing adsorber comprises a first chamber (10) including a first adsorbent (13). This first chamber is fed with humid gas from an output of the last stage (1 c) of the compressor and it delivers dried gas for a user. The pressure swing adsorber further comprises a second chamber (20) including a second adsorbent (23) which may previously have adsorbed moisture from the gas. In order to regenerate the second adsorbent and to desorb the moisture, a part of said dried gas is fed into the second chamber and the second chamber is vented into an interstage gas inlet (5) of the compressor instead of into the atmosphere, thereby improving the total efficiency of the method. A device for implementing this method is also provided.
