AZD – Azeotropic and Zeotropic Data in Non-Electrolyte Mixtures
The AZD data bank contains experimental azeotropic and zeotropic information for a very large number of binary and multicomponent mixtures. This information is of foremost importance for the design of thermal separation processes including the liquid and vapor phase. Besides the fact that knowledge about azeotropic behavior and the composition of azeotropic mixtures as function of temperature and pressure has to be known, these data also present a very vital test for the thermodynamic models and parameters used for process simulation. If azeotropic behavior is not reproduced by the thermo-package or azeotropic points are falsely predicted, simulation results will in most cases be totally unrealistic. Often a less accurate description of the VLE behavior is accepted in order to reproduce the important azeotropic behavior (ACT) and the behavior at infinite dilution with high precision.
Azeotropic points with entrainers are often used to break an azeotrope between the key components or to simplify their separation (azeotropic distillation). DDB-AZD is therefore of great importance in process synthesis for the selection of potential entrainers and should be licensed together with the DDBSP-Synthesis package (in case of extractive distillation, the most important information is found in DDB-ACT).
