This new edition includes brand-new developments in the modeling of processes in the column
apparatuses. It analyzes the radial velocity component and axial variation in the axial
velocity in the column. These models are described in five new chapters.The book presents
models of chemical and interphase mass transfer processes in industrial column apparatuses
using convection-diffusion and average-concentration models. It also introduces average
concentration models for quantitative analysis which use the average values of the velocity
and concentration over the cross-sectional area of the column. The new models are used to
analyze a broad range of processes (simple and complex chemical reactions physical and
chemical absorption physical and chemical adsorption catalytic reactions in the cases of
physical and chemical adsorption mechanism) and make it possible to model sulfur dioxide gas
purification processes.
