Zusammenfassung:	The invention relates to a method and a plant for effecting a mass transfer between a liquid and a granular solid, in which the solid is in a fixed bed arrangement in a loop circuit, the liquid being sent to part of said fixed bed through inlets and outlets which are moved forward stepwise upon exhaustion of the solid, the process liquid being replaced, in the exhausted part, by a stripping liquid, the inlet and the outlet of which are also moved stepwise forward as the transfer zone is moved.
