Sahebdelfar (2008) have developed a simple model to predict the performance of a moving bed reactor for isobutane dehydrogenation. The reactor was assumed as a simple packed bed reactor. The predicted conversion of the second reactor well matched with the plant data. However, the conversion of first reactor was underestimated while the conversion of third reactor was overrated. Sahebdelfar et al. (2011) used discretization method to model the radial moving bed reactors. The conversion, catalyst activity, and temperature profile were generated for the axial and radial

A mixture of galacto-oligosaccharides and non-prebiotic sugars was separated using a simulated moving bed unit equipped with eight packed-bed columns of a cation exchanger. In order to determine operating conditions using triangle theory, equilibrium adsorption isotherms of galactose, glucose, lactose, tri- and tetragalacto-oligosaccharide were measured. It was found that each column of the SMB unit had a maximum separation efficiency of more than 3000 theoretical plates. The achieved purity of galacto-oligosaccharides in the raffinate stream was 99.9 %, similarly 99.9 % of extract was formed by non-prebiotic sugars lactose, glucose and galactose. The productivities in the raffinate and extract, were 0.6 g/(L h) and 2.4 g/(L h), respectively.

v e n The Moving Bed 125 The Moving Bed (fi fteenth century BC) and Seti I (early thirteenth century BC), were ambitious conquerors; others were content to administer the territory they inherited or were forced to defend against invaders. Whatever their preferences, all pharaohs had to appear in public before the people, far from their palaces, which meant they had to sleep away from their bedchambers. They still, however, had to slumber clear of the ground. They used folding travel beds. TRAVELING BEDS The tomb of the young Egyptian king Tutankhamun (late

ANWENDUNGEN at 11/2004 Modellierung und Zustandsbeobachtung von Simulated-Moving-Bed Prozessen Modelling and State Observation of Simulated Moving Bed Processes Tobias Kleinert und Jan Lunze Dieser Beitrag stellt einen neuen Ansatz zur Modellierung und Zustandsbeobachtung von chromatographischen Simulated-Moving-Bed (SMB) Prozessen vor. Ziel ist es, die aktuelle Form, Position und Bewegung der Konzentrationsprofile des SMB-Prozesses aus wenigen Konzentrationsmessungen zu bestimmen. Ausgehend von der stationären Lösung des Mo- dells des wahren Gegenstroms wird ein

Apart from the traditional "flows" and "forces", e.g., those for heat conduction and mass

MOVING-BED ION EXCHANGE WITH MAGNETIC RESINS R.J. Eldridge CSIRO, Division of Chemicals and Polymers Private Bag 10, Clayton, Victoria 3168, Australia ABSTRACT Magnetic resins provide a means of exploiting the advantages of continuous moving-bed ion exchange. These advantages include small resin inventory, compact plant and tolerance of suspended solids. Magnetic ion exchangers can be handled conveniently at small (< 100 urn) diameters and therefore offer high reaction rates. Their ability to be pumped without significant attrition simplifies plant design

ANWENDUNGEN at 4/2009 Ein Adaptiver Regler zur Einstellung der Abzugsreinheiten von SMB-Anlagen An Adaptive Controller to Regulate the Drain Purities of SMB-plants Marco Fütterer Die Simulated Moving Bed (SMB) Technologie ist ein bedeutender Trennprozess in der Ver- fahrenstechnik. Chromatographische Säulen werden zu einem Ring verschaltet und die Zu- und Abflüsse zyklisch so verändert, dass eine kontinuierliche Trennung eines binären Stoff- gemisches möglich ist. Der Prozess reagiert empfindlich gegenüber Parameterunsicherheiten und Störungen in den
