Background: The theoretical foundations of modeling and simulation of the industrial processes are presented. The thermodynamic, hydrodynamic and molecular levels of the process modeling are presented.
Method: The hydrodynamic approximations are presented in the cases of the elementary processes modeling. The industrial process modeling is presented in different steps. The first step is the formulation of the physical mechanism of the industrial process and the construction of a mathematical structure, containing the mathematical operators that quantitatively describe the individual physical effects in this mechanism. The introduction of generalized (dimensionless) variables through characteristic scales permits to be made a quality analysis of the industrial processes. Obtaining experimental data and using it to calculate the model parameters by solving an inverse identification problem leads to the final form of the mathematical model. The statistical analysis of the model adequacy leads to the practical applicability of the mathematical model.
Conclusion: On this basis, a new approach is presented for the modeling of the mass transfer processes in the column apparatuses.
