Abstract
A hydrocarbon separation process which includes a novel method of fractionating the extract and raffinate streams removed from a simulated moving bed of a selective adsorbent. The extract and raffinate streams are passed into separate fractionation columns, each having a sidecut removed above the feed point. Each sidecut is stripped, with the stripper overhead vapor passing directly into the extract or raffinate column. The bottoms streams of the two sidecut strippers are combined and passed into the adsorbent bed.
