Organic vapors are removed from a gas stream and concentrated to a high degree in a continuous adsorption process. The vapor-laden gas passes through a portion of a cylindrical-shaped adsorber as it rotates in a plane normal to the gas flow. The rotating adsorber then moves through several stages including regeneration and cooling. The vapor-laden gas is spiked with recovered product to increase the loading on the adsorbent and thus provide a higher regenerating gas composition. Multi-stage regeneration assures a high recovery efficiency.
