EQUILIBRIUM THEORY-BASED DESIGN OF SMBS FOR A GENERALIZED LANGMUIR ISOTHERM
This work presents design criteria for complete separation of binary mixtures in Simulated Moving Bed (SMB) separations that apply to systems, whose retention behavior is characterized by a generalized Langmuir isotherm. By allowing for negative terms in the denominator of the classical Langmuir isotherm, this newly introduced adsorption model covers a broad class of adsorption isotherms, including Langmuir or anti-Langmuir behavior for both adsorbates, and mixed cases where one species behaves in a Lagmuirian and the other in an anti-Langmuirian manner. By extending classical equilibrium theory results for the binary Langmuir isotherm, and by generalizing the approach followed earlier to derive SMB design criteria for the binary and multi-component Langmuir isotherm, exact algebraic equations for the boundary of the complete separation region in the operating parameter space are derived for all possible generalized Langmuir isotherm.
