The many chromatography units operating worldwide for the classical
Fructose/ Glucose separation are based on the SMB ("Simulated Moving
Bed") system, with 8 or 16 columns (or chambers). This is also true
for applications for polyols separation, purification, or enrichment.
The ISMB ("Improved Simulated Moving Bed") process patented by Mitsubishi
Chemical/ Nippon Rensui, allows equivalent performances with only
four columns (or chambers) and several other advantages.
The purpose of this paper is to present the main features of this
process, as well as the performances of the first European installation
operating for two years for the separation of sugars from non-sugars
with a Fructose syrup.
