The process drives the rectified feed (95% v/v alcohol) through
a bed of desiccant beads. To allow for bead regeneration, in the
continuous operation, twin beds are provided of which one is in
dehydration mode while other is regenerating exchanges taken place
in few minutes. In the regeneration process, absorbed water together
with the contained ethanol is released, which is recycled back to the
regeneration column for reprocessing.
