Abstract
A process is presented for the purification of an olefins feed stream to a benzene alkylation unit. The process removes heavy aromatics in an adsorbent system comprising at least two adsorbent units. The unit passes the olefins feed stream to a first adsorbent unit, while the second adsorbent unit is either in regeneration mode, or standby mode. The process switches the feed stream to the second adsorbent unit and displaces the fluid in the second adsorbent unit, while maintaining the flow of the purified feed stream to the benzene alkylation unit.
