Besides general mass and energy balances dynamic simulation and optimization of chemical processes often includes complex depiction of thermodynamic properties of occurring components. However, the use of thermodynamic models in equation-based solvers for dynamic simulation and optimization can lead to various challenges. Dependencies of thermodynamic state variables for fluid mixtures are often described by cubic equations of state (EOS). The cubic equation has up to three roots for volume V depending on states (temperature T and pressure p). Consequently, the intended root has to be selected from those, which is only partly possible in equation-based development environments for simulation and optimization. In order to still incorporate advantages of EOS, artificial neural networks (ANN) can be applied.

In this work, the use of ANN for grey box modeling of thermodynamics in context with dynamic optimization is to be investigated.
