Disclosed are sorption bed systems and methods of operating sorption bed systems of the type used to remove and recover plural dilute species from a fluid stream. The system comprises a main bed which is loaded during sorption duty, and a sorbate recovery, main bed-regeneration apparatus comprising a second sorption bed for separating the dilute sorbates, a sorbate collecting device such as a condenser, and optionally, when regeneration and sorbate recovery is conducted in a recirculating fluid mode, a third sorption bed downstream of the sorbate collecting device for improving the yield of sorbate recovery. Practice of the invention is characterized by a significantly reduced heat consumption and the collection of sorbate fractions of improved purity.
