Purification of gases in the chemical industries is ever evolving field in terms of clean technology and cost effectiveness. The flue gases need to be treated for removal of particulate matter (PM), gases like oxides of sulfur, carbon and metals. This can be done by adsorption, bag filters, cyclones (PM), absorption etc. Adsorption is also very effective for this treatment. Also adsorption finds application of cleaning air for instrumentation and process applications. The regeneration of adsorbents and recovery of valuable gases is an important aspect of the adsorptive separation. Temperature and pressure swing (TSA and PSA) adsorption uses change in temperature and pressure respectively for regeneration. Current review summarizes research and studies on PSA, as it is widely used technique.

Key words: Regeneration, recovery, vacuum, recovery, purity.
