Method for obtaining a substantially dehydrated desorbate in the desorption of sorption materials loaded with a gaseous, recirculated desorption medium. The desorption medium is heated up in a first heat exchanger before it enters into the loaded sorption material. Desorbate is removed from the desorption medium by cooling in a second heat exchanger acting as a desorbate condenser, and water vapor is removed at least partially by adsorption in an adsorptive drier. The cooled and dried desorption medium is returned by a circulating blower to the first heat exchanger. The desorption medium before entering into the adsorptive drier, is cooled down in the initial phase of the desorption period in the desorbate condenser, first, to near the water saturation limit. The cooled-down desorption medium with the water vapor saturation which is high in this initial phase, flows toward the adsorptive drier and is subsequently heated in dry condition. In the desorption phase following the initial phase the desorption medium loaded with desorbate is cooled completely in the desorbate condenser. During the cooling phase following the desorption phase, the desorption medium which now leaves the sorption materials in hot condition flows, uncooled, toward the adsorptive drier.

Method for obtaining a substantially dehydrated desorbate in the desorption of sorption material loaded with adsorbed material, in particular a solvent, and water, which comprises recirculating a gaseous desorption medium during a desorption period constituting an initial phase, a following desorption phase proper and a following cooling phase, through a first heat exchanger wherein the desorption medium is heated, passing the heated desorption medium in contact with the loaded sorption material to effect removal of adsorbed material and water, discharging the desorption medium containing desorbate and water from the sorption material and cooling said desorption medium in a second heat exchanger acting as a desorbate condenser to remove desorbate, passing the cooled desorption medium from the second heat exchanger to an adsorption drier to remove water vapor from the desorption medium, at least partially, by adsorption in the drier, and recirculating the cooled and dried desorption medium from the drier to the first heat exchanger, the combination therewith wherein the desorption medium before entering the adsorptive drier is in the initial phase of the desorption operation cooled in the desorbate condenser to near the water saturation limit, wherein said cooled-down desorption medium near water vapor saturation which is high in the initial phase flows toward the adsorptive drier and is subsequently heated in dry condition, wherein in the desorption phase proper following the initial phase, the desorption medium loaded with desorbate is cooled to a low temperature to cool the adsorptive drier and retain water therein, and wherein in the cooling phase following the desorption phase proper, the desorption medium which now leaves the sorption materials in hot condition flows, uncooled, toward the adsorptive drier.
