Abstract

Loaded solid resin particles obtained as an output slurry from a continuous fluid/solid contactor are stripped by counter-current elution in which discrete measured batches of the loaded resin are isolated, each batch is drained of its carrier liquid, and successive drained batches are then slurried intermittently into the bottom of an elution column using strong eluate from the elution column to slurry the resin into the bottom of the column.
