Abstract
A rotary adsorption unit is disclosed wherein the desorb air is supplied by a regenerative thermal oxidizer. The system utilizes a closed desorb loop, with the desorb air being continuously cleaned at the regenerative thermal oxidizer and returned to the rotary adsorption unit. Fresh air is added into the desorb gas on the way to the regenerative thermal oxidizer, and an equal amount of air is bled off to maintain a constant air flow. The added air replaces oxygen that may be lost during cleaning of the desorb air.
