Dynamic holdup in a countercurrent gas - flowing solids - packed bed contactors

Abstract

Equations for the prediction of the holdup of dynamic solids in countercurrent gas – flowing solids – packed bed contactors are presented in this paper. The correlations do not require the use of parameters that need to be determined by experimental measurements in the actual system of interest. They could be used for a wide range of operational conditions, different packing types and a variety of flowing solids materials. The equations are compared with all available experimental data from the literature.
