New models of industrial column chemical reactors

A new approach to modeling the industrial column chemical reactors is presented. A theoretical analysis of the effect of the radial non-uniformity of the axial velocity component in the industrial column chemical reactors is presented. A numerical analysis shows, that average concentration model, where the radial velocity component is equal to zero (in the cases of a constant velocity radial non-uniformity along the column height), is possible to be used in the cases of an axial modification of the radial non-uniformity of the axial velocity component. The use of experimental data, for the average concentration at the column end, for a concrete process and column, permits to be obtained the model parameters, related with the radial non-uniformity of the velocity. These parameter values permit to be used the average concentration model for modeling of different processes.
