Abstract
A two stage rotary concentrator takes the gas from the first stage desorption section and passes it back into a second stage concentrator process. A second stage desorption gas is passed over the rotary concentrator in a second stage desorption section. The gas from the second stage desorption section may then be passed for final treatment. The invention greatly reduces the volume of air which must be sent for final treatment.
