ABSTRACT:
To regenerate the adsorbent which serves to purify compressed air from water and carbon dioxide, there is used residual gas from an air distillation apparatus (10), heated to a substantially constant moderate regeneration temperature between the temperature of the air entering the mass of adsorbent and a temperature which is at most about 50.degree. C. higher, preferably about 10.degree. to 20.degree. C. higher, than this entering air temperature. This gas is then sent to a water refrigeration tower (16) for cooling the compressed air.
