Modeling of Superheated Steam Thi Thu Hang Tran Drying in Packed Bed

Abstract

The continuum-scale model of packed bed superheated steam drying of ceramic particles is presented in this
paper. The mass transfer between particles and agent is described in this model using the Reaction Engineering
Approach (REA) model. The dehydration of porous particles is modeled in the REA as a process that requires
activation energy to cross an energy barrier. After a successful validation, the continuous heat and mass
conservation equations of the bed are integrated with the single particle drying model to simulate the drying
process. The scaling-up technique suggested in this work can be used to characterize superheated steam dryers,
according to the initiative results from the bed simulations.
