Abstract
The invention provides an energy-efficient process and apparatus for removing adsorbed material, such as organic solvents, from an adsorber. In a first step, heat from a heat storage means is used to desorb both the adsorber and an auxiliary adsorber. Once the auxiliary adsorber is desorbed and cooled, desorption of the adsorber continues as the solvent is removed in a condensing system. Once the adsorber has been thoroughly heated, the flow of gas therethrough is reversed, thereby transferring heat back to the thermal regenerator and effecting further desorption from the main adsorber, the material thus desorbed being captured in a condensing system and in the auxiliary adsorber.
