Modeling of column apparatus processes (Second edition.)

A new approach for the modelling of chemical and interphase mass transfer processes in industrial column apparatuses, using convection-diffusion and average-concentration models.

The convection-diffusion type models are used for a qualitative analysis of the processes and to assess the main, small and slight physical effects, and then reject the slight effects.

As a result, the process mechanism can be identified.

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.
