Abstract

Three phase fluidization is an effective technique to achieve sufficient mixing of phases, with better mass and heat transfer rates. The economical design and operation of the fluidized bed needs to study the hydrodynamic characteristics for better performance. The present work is an experimental investigation on the hydrodynamic behavior of a co-current three phase fluidized bed with liquid as a continuous phase in a 54 mm id Perspex (Acrylic column) with particle size of 4.38, 3.89 and 1.854 mm glass beads. Based on the experimental work, the various parameters such as pressure drop, porosity, gas and liquid holdups were studied and the observed data was reported.

Keywords
