Pressure drop in spouted beds.

Abstract

The present work contains the result of an investigation on pressure drop in sprouted beds. Six inch columns with a 0.5" air inlet orifice were used during the course of the investigation. The spouting medium was air. The gas flow rates vary from 84 to 1077 pounds per hour per square foot of column cross section. Particle diameters ranging from 0.079" to 0.25" were studied. Porosities of the packings vary from 0.358 to .0525. Correlations for the packed bed region and for the spouting point are presented. A six inch spouting unit consisting of four stages was also studied. Necessary gas flow rates to achieve spouting in each stage seems to indicate that the spouting bed technique can be improved by using several stages instead of one.
