CONTINUOUS SEPARATION OF GLUCOSE-SALTS MIXTURE WITH NONLINEAR AND LINEAR ADSORPTION ISOTHERMS BY USING A SIMULATED MOVING-BED ADSORBER

Abstract

Continuous glucose/NaCl separation was successfully performed by using a simulated moving-bed adsorber packed with ion-retardant resin. Two kinds of mathematical models, i.e. an intermittent moving-bed model and a continuous moving-bed model, were proposed to calculate concentration profiles in the adsorber where the adsorption isotherms of the first component (NaCl) and the second component (glucose) are represented respectively by the Langmuir equation and by a linear equation. The validity of the calculation methods proposed was experimentally confirmed.
