Detailed description of topics:

Calculation of heat capacity and enthalpy and Gibbs energy of reaction data. Use of equations of state necessary for the calculation of thermodynamic quantities. Estimation of thermodynamic data, using e.g. the corresponding states principle and group contribution methods. Non-ideal behaviour of pure substances and mixtures whereby properties of the chemical potential, the fugacity and the activity will be considered. The notion of exergy as used for chemical conversions. Application to physical processes, such as separations and chemical reactions, like combustion/gasification.

Course material:

  • J.M. Smith & H.C. van Ness, introduction to Chemical Engineering Thermodynamics, 6th edition, McGraw-Hill Book Company

References from literature:

  • R.C. Reed, J.M. Prausnitz and B. E. Poling, The properties of Gases and Liquids, 4th ed., Mc. Graw-Hill Book Company

Remarks assessment, entry requirements, etc.:

Make use of TAS to subscribe for the exams. By making 10 problems during the lecture period, three extra marks for the written examination can be obtained. The book of Smith&Van Ness must be used during the written examination.

Learning goals:

The student must be able to:

  1. formulate "equations of state" (EOS), describe their physical background and to select them appropriately for given process conditions (pure components)

  2. estimate thermodynamic data from the "corresponding states principle" and "chemical group contribution" methods (pure components)

  3. calculate (physical) phase equilibrium behaviour for vapor-liquid and liquid-liquid systems of multi-component ideal mixtures

  4. calculate (physical) phase equilibrium behaviour for vapor-liquid and liquid-liquid systems of multi-component non-ideal mixtures

  5. recognize the important role partial molar properties play in mixture phase equilibrium calculations, and to perform these type of calculations

  6. calculate the extents of chemical reaction equilibria and resulting mixture compositions in ideal and non-ideal mixture gas and vapour-liquid systems

  7. calculate heat effects occurring in chemical equilibrium reactions

Computer use:

.Problems are given to students to determine non-ideal mixture behaviour; the use of the computer (excel, mathcad etc.) is indispensable.
