Abstract: A process providing continuous or quasi-continuous sorption uses at least three fixed bed sorbent zones connectable in series by pipes, for the passage of a liquid phase containing a component to be sorbed. The approach of saturation of one or more of the zones is detected, e.g., using temperature sensors, and regeneration of the saturated zone or zones is initiated using hot gas. Compared to conventional sorption processes, energy savings, especially as regards energy consumed in blowing the hot gas through the fixed bed zone, are obtainable.
