Abstract
A process for determining by simulation the optimum stabilization conditions of a simulated moving bed (SMB) separation system allows to obtain set values for the purity of an extracted constituent and for the efficiency. In order to determine the optimum flow rates, a single simulation is carried out, which includes a succession of stages intended for rectification of the fluid flow rates during limited time intervals (T), including each, after each time interval, comparison of the respective purity degrees and efficiencies obtained, resulting from situations stemming from simulations over a time interval (&Dgr;t) where rectifications are applied to at least one flow rate, with those of a reference situation resulting from a simulation over the same time interval but without flow rate rectification, followed by a selection of flow rates aimed to minimize the quantity of impurities in the extract and the quantity of constituent in the raffinate.
