Abstract
According to this process, compressed air is cooled and purified by adsorption by passing same in a first direction through a mass of adsorbent material (8), then a residual gas from the distillation apparatus passes in opposite direction through this mass to regenerate same. During the entire regeneration, the residual gas is at a constant regeneration temperature which is between the temperature of the air entering into the mass of adsorbent material and at a temperature which is about 50.degree. C. above this temperature.
