We outline here some of the steps we are taking towards the development of reliable tools for quantitative predictions of thermodynamic properties of complex fluids with equations based on statistical mechanics. The long term objective is to provide a user-friendly computer code and a wide database of molecular parameters for different compounds, able to be implemented in a process simulator. We have observed that the keys of the success when using molecular modelling tools for predictions rely on the selection of the appropriate model, representative of the molecular structure, and the use of physically meaningful molecular parameters.
