Modeling of Column Apparatus Processes

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.

Presents a new approach for modeling heat and mass transfer processes in column apparatuses Two new chapters round out the overview of new modeling approaches in the new edition Offers a new continuum-mechanical approach to solve the mass transfer problem Equips readers to qualitatively analyze the main, small, and slight physical effects of processes
