ABSTRACT:
A continuous and valveless sorber device is described which utilizes a novel rotating sorption bed which operates through at least three zones (sorption, desorption and cooling). The rotating sorption bed is contained within a plurality of manifolds and the sorption bed and the manifolds are sealed to one another via sealing means. Contaminated fluid is directed through the sorption zone of the rotating sorption bed where the contaminants are removed by sorbents. The bulk of the fluid which is then cleaned is available for use. A portion of the clean fluid (regeneration fluid) is used to cool the sorbent in the cooling zone of the rotating sorption bed. The warmed regeneration fluid is then heated by a regeneration heater and is subsequently directed into the desorption zone of the rotating sorption bed where the hot clean regeneration fluid is used to desorb and carry away the contaminants from the sorbent. The hot contaminated regeneration fluid, which has a reduced flow rate but a higher concentration of contaminants than the original fluid stream, may then be disposed of or processed in a suitable manner.
