Abstract
Recently, different strategies for improving simulated moving bed (SMB) chromatographic separation processes have been proposed, including a modulation of the feed flow and the feed concentration during the tacts. In this contribution these two different strategies are applied to a benchmark problem and are compared with each other. Physical explanations of the improvements obtained compared with the conventional operation mode are given in terms of moving concentration fronts. Practical aspects for the implementation of the different strategies are also discussed. copyright 2003 Elsevier Ltd. All rights reserved. [accessed 2013 November 29th]
