SIDE-OUTLET SPOUTED BED WITH DRAFT TUBE - EFFECT OF VARYING THE POSITION OF THE OUTLET

The vector form of the Ergun equation was used to numerically predict gas phase streamlines, residence time distributions, chemical conversi ons and pressure drops in the annulus of a side-outlet spouted bed wit h an internal draft tube. By varying the position of the side-outlet, it was demonstrated that there exists an optimum location for this out let at which conversion is a maximum and which shows a greatly improve d gas phase residence time distribution in the annulus compared with a conventional spouted bed unit.
