Selecting the Right Thermodynamic Models for Process Simulation

By Atul B. Choudhari |

Software that enables complex processes to be simulated continues to evolve for a wide range of thermodynamic conditions. Selection of the most appropriate models plays a crucial role in adequately representing real-life conditions One of the first and most important decisions to be made when modelling a chemical process system using a computer simulation package is the selection of an appropriate method for simulating thermodynamic properties. Thermodynamic-property methods enable the mathematical calculation of pressure, temperature, composition and specific volume for multi-component and multi-phase chemical systems. These calculation methods are also used as a basis for determining the state functions of a system, such as enthalpy and entropy and hence, Gibbs free energy. This article provides an overview of the primary thermodynamic-property methods, and discusses the basis that underlies each one, the strengths and weaknesses of each, and applicability of each to various chemical systems, to assist in the selection decision. In general, thermodynamic-property methods can be categorized according to the following four options (each of which is discussed in greater detail below): 1. Equations of state (EOS). These are primarily…
