Introduction
In a new book (Chr. Boyadjiev, M. Doichinova, B. Boyadjiev, P. Popova-Krumova, “Modeling of Column Apparatus Processes”, Springer-Verlag, Berlin Heidelberg, 2016, pp. 313.) is presented a new approach for the modeling the processes in column apparatuses, using the physical approximations of the mechanics of continua in the cases of a constant radial non-uniformity of the axial velocity component in the column.

The presented convection-diffusion type models are used for a qualitative analysis of the processes and are a base of the average concentration models, which allow a quantitative analysis of the processes in column apparatuses.

Very often in industrial conditions, an axial modification of the radial non-uniformity of the velocity, is realized. This radial non-uniformity of the axial velocity component in the column apparatuses is caused by the fluid hydrodynamics at the column inlet, where it has as maximum and decreases along the column height as a result of the fluid viscosity.

In the Special Issue will be presented the possibilities to be modeled the industrial processes in column apparatuses in the cases of homogeneous chemical reactions, physical and chemical absorption, physical and chemical adsorption and heterogeneous catalytic reactions.
