In **Figure 20** the behavior of the liquid in each of the stages of the column is shown (**Figure 21**), it is observed that in the initial stages there is a transfer of both mass and energy, this can be verified in **Figure 22** where shows the temperature profile across the reactive column, in **Figures 23** and **24** represent the liquid and vapor profiles in each of the stages.

In the same simulations, comparisons were made between thermodynamic properties such as: Enthalpy and Entropy, these used in the thermodynamic models used.
