Thermodynamics of Chemical Processes

Building on the fundamentals of thermodynamics and mixture and process thermodynamics, this module explores key issues in chemical and thermal process engineering. The focus is on chemical reactions, their thermodynamic description and kinetic modeling, as well as their extension to electrochemical systems and complex material models.

Students learn to calculate reaction equilibria, taking into account stoichiometry, reaction progress, and relevant material data. Reaction enthalpy, reaction entropy, and Gibbs energy are systematically derived and classified in the context of the third law of thermodynamics. In addition, the fundamentals of electrochemistry are covered in order to transfer thermodynamic concepts to electrochemical processes.

Another focus is on the description and calculation of thermodynamic state variables, including for complex fluids. Students will be able to analyze phase behavior, construct equations of state from measurement data, and apply suitable material models and estimation methods. Important material data such as heat capacities, vapor pressure curves, and evaporation and formation enthalpies are systematically covered.

In addition, students acquire the ability to independently research and interpret reaction kinetics and classify them in engineering contexts. The module thus provides a sound basis for the thermodynamic and kinetic description of complex reaction and material systems in process engineering.
