  • Two stage rotary concentrator
    Patent number: 5891219
    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.

  • Rotary adsorption unit with regenerative thermal oxidizer
    Patent number: 5567229
    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.
