Abstract: Improved product purity is provided in a simulated moving bed adsorptive separation apparatus by flushing the stagnant volume of the feed valve and the transfer line connecting the feed valve to the rest of the apparatus. The invention adds another line for delivering recycle fluid as the flush stream to an additional inlet port on the feed valve. The apparatus comprises a number of serially connected adsorbent-containing chambers. The chambers are linked together with valving necessary to simulate the continuous countercurrent flow of the adsorbent and liquid phases.
