DIFFUSION MODELS AND SCALE-UP

Abstract

A model for transfer processes in column apparatuses has been done. The model may be modified for different apparatuses as columns with (or without) packet bed, two (or three) phase airlift reactors and fluidized bed reactors. The mass transfer is result of different volume reactions as a chemical, photochemical, biochemical or catalytic reactions or interphase mass transfer. The using of the average velocities and concentration permit to solve the scale - up problems. A hierarchical approach for model parameter identification has been proposed. Key words: diffusion model, scale - up, average velocity, average concentration, scale effect, column, airlift, fluidized bed, volume reaction.
