<p>A process providing continuous or quasi-continuous sorption uses at least three fixed bed sorbent zones (A-E) connectable in series by pipes (3), 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 (17), and regeneration of the saturated zone or zones is initiated using hot gas. The procedure may be applied to the removal of water from ethanol/water mixtures using zeolite sorbent. <IMAGE></p> |
