Abstract
A rotary concentrator heats media in a desorption zone to a desorption temperature, then removes the pollutants using a second cold desorbent gas stream in a desorbent zone. First, the adsorbent media is rotated and an inlet gas stream is passed over the media in the adsorbent zone, thereby removing the adsorbable pollutants. A first gas stream having a temperature equal to or greater than the desorption temperature of the adsorbable pollutants is passed over the media in the desorbent zone to heat the media to generally the desorption temperature of the adsorbable pollutants. A second gas having a temperature less than the desorption temperature of the adsorbent media is passed over the media in the desorbent zone to remove the adsorbable pollutants from the desorbent zone. Subsequently, the gas containing the adsorbable pollutants received from the desorbent zone is processed by destroying or removing the adsorbable pollutants.
