Approaches to thermodynamic property calculation of complex fluids: literature review

Thermophysical properties of industrially complex fluids whose composition is always ill-defined are in practice predicted by using thermodynamic models. To ensure the prediction accurately and reliably, a three-step procedure to obtain the properties of these fluids must be validated. The focus of this study is laid on a short review of tools which can be served for each of the three steps. It should be noted that the tools presented in this work are centered on the ones applicable for highly associating and/or polar fluids. It is also recommended in this work an approach for characterizing a pseudocomponent representative of a complex mixture, e.g. petroleum fluids, biomass fluids, considering the available analytical data. This fully described pseudocomponent can be easily used within any thermodynamic models
