Design of a simulated moving bed unit for sucrose-betaine separations

The results of a series of pulse experiments carried out in a fixed bed col umn packed with a strongly acid ion-exchange resin and with reference to th e separation of an aqueous sucrose-betaine mixture are presented. These dat a were used to evaluate equilibrium and diffusion parameters for both key c omponents in the frame of linear chromatography theory. The estimated value s were used to design a simulated moving bed plant aimed to separate betain e from sucrose in beet molasses. (C) 2000 Published by Elsevier Science BN. All rights reserved.
