Chromatography has been a method of choice in the separation of complex biological mixtures for the analytical purpose in particular for the last laif of century. Recently, simulated moving bed(SMB) method which claims high separation efficiency of the ideal counter-current moving bed chromatography has become a workhouse of preparative separation. In this study, the SMB model is used for bioethanol production, the conditions for separating polysaccharide, were determined by triangle theory and simulations using the gPROMS software. The SMB model assumed an axial dispersion flow for the liquid phase and the intraparticle mass transfer was described in terms of a simple Linear Driving Force (LDF) approximation. The parameters of the Langmuir Adsorption Isotherm (LAI) were determined using a dynamic method. In the optimal condition the calculated concentrations were confirmed by the experimental results. Values projected by the gPROMS software more closely matched experimental values than those projected by the Aspen Chromatography package. |
