<p>The process for removing impurities from a liquid by contact with a solid adsorbent using parallel contact adsorbent beds such that when one bed is contacting the liquid the parallel bed is being regenerated by contact with heated inert gas, wherein during changeover of the beds inert gas is transferred from the regenerated bed to the spent bed during the period that liquid is being drained from the spent bed.</p> |
