Abstract
There is disclosed an improved PSA process for the pre-purification of air to remove water vapor and carbon dioxide prior to introduction into an air separation unit. The subject process includes a step of efficiently regenerating the adsorptive beds utilized to remove the impurities wherein they are first vented to the atmosphere, then evacuated with atmospheric venting and finally purged under evacuation. Preferably, a pair of adsorptive beds operating out of phase undergo top and bottom pressure equalization prior to backfilling of the bed completing regeneration.
