Process and apparatus especially for saving energy at the regeneration of active carbons containing adsorbed solvents

Abstract

Abstract 1. Process usable for regenerating an active charcoal containing at least one adsorbed solvent, process according to which said activated active charcoal is treated in an adsorber by steam with the steps of condensing vapours issuing from said adsorber, decanting the condensed product and recycling the water resulting from the decanting, said process being characterized in that : - the vapours issuing from said adsorber pass through an indirect exchanger (6) in which they yield part of their calories to an impure water (10) while producing impure water vapour at a pressure of between 0.1 and 1 bar, said vapour being taken up by an ejector and recycled in said adsorber, - and said indirect exchanger is supplied with impure water coming out of the decanter in which said decantation has been carried out.
