What is chemical process calculation

The classical thermodynamics of simple systems

Applied Statistical Thermodynamics pp 1-21 | Cite as


In the applications of thermodynamics, material properties of fluids play a paramount role. The cycle processes of the energy conversion systems and the process energies converted in them are influenced to a large extent by state variables such as the volume, the enthalpy and the entropy of the working media. In technical thermodynamics [1–6] it is shown how these state variables are included in the process calculation. Process engineering systems are often based on phase and reaction equilibria in mixtures. In chemical thermodynamics, the relevant thermodynamic conditions for such states of equilibrium are generally formulated by thermodynamic functions, in particular the chemical potential [7–12]. All in all, these different aspects of the material behavior of fluid systems are covered by a closed and well-documented network of general equations: the equation framework of classical thermodynamics.
