Abstract:
A desorption system for continuously desorbing a sorbate from a sorption media, comprising:a source of microwaves having properties for separating the material from the sorption media; a conduit coupled to the source of microwaves for directing the microwaves along an energy flow path; a media flow shaper disposed in the energy flow path and being adapted to receive the sorption media with the sorbate sorbed onto the sorption media, the media flow shaper facilitating a flow of the sorption media; a wall included in the media flow shaper for directing the media flow path transverse to the energy flow path, the wall being disposed between the media flow path and the source of microwaves and having properties transmissive of the microwaves; whereby, the conduit directs the microwaves through the wall and into the media flow path to desorb the sorbate from the sorption media; a source of inert gas disposed outside the media flow shaper; a conduit coupled to the gas source for directing the inert gas along a gas flow path transverse to the media flow path; the wall being transmissive of the gas to permit the gas to pass into the media flow path and carry the desorbed sorbate away from the media; wherein: the wall is a first wall; the media flow shaper includes a second wall defining with the first wall the media flow path; the first wall is porous to the gas; and the second wall is porous to the gas and the desorbed sorbate; and a third wall disposed on the side of the second wall opposite the first wall and having properties for reflecting the energy back through the second wall and into the media.
