The thermodynamic properties and phase behaviors of pure fluids and their mixtures are very important in food, chemical, and pharmaceutical industry, especially for the design and optimization of separation processes. For example, the information regarding temperature, pressure, and composition in vapor-liquid equilibrium (VLE) and liquid-liquid equilibrium (LLE) is crucial for the design of distillation and extraction processes. The solubility of pharmaceuticals in pure and mixture solvents are of great importance in design of purification processes in pharmaceutical industry. It is straightforward and might be the most reliable way to obtain the needed data directly from experimental measurement, but a reliable predictive model can significantly reduce the time, cost, and risk for problems involving extreme operation conditions and/or toxic chemicals. Therefore, both approaches are equally important to obtain such data. In my previous research, three different research topics are considered: (a) development of first-principle thermodynamic model to predict a wide variety of thermodynamic data for pure fluids and mixtures, (b) using molecular simulation as a tool to generate theoretically-based data for the development of thermodynamic model and to provide necessary VLE data, (c) measuring VLE data at high pressure condition. All these three topics are briefly summarized in this presentation.
