The Dynamic Simulation of Chromatographic Separation of Citric Acid

Abstract

Abstract: This paper provides a suitable method for studying thermal swing chromatographic kinetics and estimation of model parameters, considering the change of bed porosity. As an experimental example, the separation of the citric acid is discussed. The model parameters were measured on an analytical column. With these thermodynamic parameters it was attempted to simulate the separation behaviour in larger columns using the equilibrium dispersive model, the result was very satisfactory.

Key words: Equilibrium dispersive model, Thermal swing, Bed porosity, Kinetics, Simulation, Citric acid
