ABSTRACT:
A cyclic adsorption process is provided in which two zones are employed--an adsorption zone and a heat storage zone. A fluid stream containing a solute to be removed therefrom is passed through the adsorption zone and the effluent is then passed through heat storage zone. The conditions under which the stream is passed through the adsorption zone are selected so that the rate of progression of the heat transfer front and mass transfer front are substantially equal. This results in an optimum temperature of the effluent stream for efficient heat recovery in the heat storage zone. During regeneration of the adsorbent, a fluid regenerating stream is passed through the heat storage zone where it is partially heated. At a point between the adsorption zone and the heat storage zone the regenerating fluid stream is further heated, via an additional heat source, and passed through the adsorbent zone. The amount of additional heat is sufficient to effectively desorb the adsorbent. Alternatively, of course, a pressure reduction and a combination of heat addition and pressure reduction may be employed to desorb the adsorbent.
