Use of Two Feeds in Simulated Moving Beds for Binary Separations

Simulated moving bed (SMB) and Analog systems with two-feeds are proposed to increase the separationperformance. Operation with both total and partial feeds is studied. When the two feeds have diferent compositions,the proposed SMB system often showed better performance than conventional SMB and Varicol systems and the Analogsystem with two-feds typically achieved higher purities compared to the Analog for conventional SMB and Varicoloften showed significant performance improvement compared to conventional SMB plus partial feed and Varicol pluspartial feed. When the two feds are identical, partial feed operation of the two-feed SMB becomes identical to partialfeed operation of Varicol. KCI Citation Count: 11
