Title: Double barrier as an effective method for slower delivery rate of
ibuprofen
ABSTRACT:
The hydrodynamic behaviour of a pseudo-2D Two-Section Two-Zone Fluidized Bed
Reactor (TS-TZFBR) with an immersed tube bundle in its lower zone has been
studied using non-invasive Particle Image Velocimetry (PIV) and Digital
Image Analysis (DIA). Coupled porosity distribution maps from DIA post-
processing and solids velocity vector fields from PIV analysis allowed the
reconstruction of the transient and time-averaged solid fluxes along the bed
. Six different tube bank configurations at several different superficial
gas velocities have been tested to evaluate the hydrodynamic behaviour
within the lower zone of the TS-TZFBR. The solids axial mixing along the
vertical bed position has been quantified for this novel reactor
configuration. Besides, the effect of the internals on the gas-solid mass
transfer has been estimated by means of bubble size. A five-staggered tube
bundle configuration was able to diminish the average bubble size by 30%
within the lower bed zone at usual TS-TZFBR gas flow rates, ugas/umf = 3.0,
without increasing the solids circulation time dramatically.
