The complex processes in the column apparatuses have a combination of hydrodynamic processes, convective and diffusive mass (heat) transfer processes and chemical reactions between the reagents (components of the phases).
In the book is presented a new physically motivated approach for the modeling of column apparatus processes in industrial conditions, using the mechanics of continua. In the Introduction was showed that the presented mass transfer theory is not applicable for the modeling of column apparatus processes in industrial conditions, because the velocities in each phase and the phase surfaces in columns are unknown and practically cannot be deter-mined.
The modeling of column apparatus processes is made, using two type models as convection-diffusion and average concentration models, where as an innovation is the process mechanism identification on the base of the Guhman's generalized analysis. In the book are presented these models of one, two, and three phase processes.
