A process for the removal of heavy aromatics from an olefins stream comprising: passing an olefins feed stream to a first adsorbent unit in two unit adsorbent system to generate a first adsorbent effluent stream with reduced heavy aromatics content; running the first adsorbent unit until breakthrough; equalizing pressure in a second adsorbent unit to the pressure of the first adsorbent unit; passing the olefins feed stream to the second adsorbent unit to generate a second adsorbent unit effluent stream with reduced heavy aromatics content; passing the second adsorbent unit effluent stream to the first adsorbent unit, displacing the first adsorbent unit fluid; discontinuing the first adsorbent unit displacement and moving the first adsorbent unit off-line and the second adsorbent unit on-line; performing a trim displacement of the first adsorption unit following the first adsorption unit displacement; passing regenerant to the first adsorbent unit to regenerate the first adsorbent unit, wherein the regenerant flows in a co-current direction relative to the olefin feed stream through the first adsorbent unit; equalizing the pressure in the first adsorbent unit to the pressure of the second adsorbent unit; passing the olefins feed stream to the first adsorbent unit to generate the first adsorbent unit effluent stream; passing the first adsorbent unit effluent stream to the second adsorbent unit, displacing the second adsorbent unit fluid; discontinuing the second adsorbent unit displacement and moving the second adsorbent unit off-line and the first adsorbent unit on-line; performing a trim displacement of the second adsorption unit following the second adsorption unit displacement; and passing regenerant to the second adsorbent unit to regenerate the second adsorbent unit, wherein the regenerant flows in a co-current direction relative to the olefin feed stream through the first adsorbent unit. passing an olefins feed stream to a first adsorbent unit in two unit adsorbent system to generate a first adsorbent effluent stream with reduced heavy aromatics content; running the first adsorbent unit until breakthrough; equalizing pressure in a second adsorbent unit to the pressure of the first adsorbent unit; passing the olefins feed stream to the second adsorbent unit to generate a second adsorbent unit effluent stream with reduced heavy aromatics content; passing the second adsorbent unit effluent stream to the first adsorbent unit, displacing the first adsorbent unit fluid; discontinuing the first adsorbent unit displacement and moving the first adsorbent unit off-line and the second adsorbent unit on-line; performing a trim displacement of the first adsorption unit following the first adsorption unit displacement; passing regenerant to the first adsorbent unit to regenerate the first adsorbent unit, wherein the regenerant flows in a co-current direction relative to the olefin feed stream through the first adsorbent unit; equalizing the pressure in the first adsorbent unit to the pressure of the second adsorbent unit; passing the olefins feed stream to the first adsorbent unit to generate the first adsorbent unit effluent stream; passing the first adsorbent unit effluent stream to the second adsorbent unit, displacing the second adsorbent unit fluid; discontinuing the second adsorbent unit displacement and moving the second adsorbent unit off-line and the first adsorbent unit on-line; performing a trim displacement of the second adsorption unit following the second adsorption unit displacement; and passing regenerant to the second adsorbent unit to regenerate the second adsorbent unit, wherein the regenerant flows in a co-current direction relative to the olefin feed stream through the first adsorbent unit. <EOS>
