CHEN 3320: CHE Thermodynamics Department of Chemical and Biological Engineering John L. Falconer ——————————————————————————— ---- ———————————— Learning Objectives : Chapter 8 (Elliott-Lira) At the end of this chapter you should be able to: 1. Remember the fundamental property relation for Gibbs free energy. 2. Explain why fugacity and not concentration is the driving force for mass transfer. 3. Explain why the fugacity of a saturated liquid is close to the vapor pressure of the liquid. 4. Calculate sat P f , , from the Peng-Robinson EOS spreadsheet. 5. Explain why the fugacity for a liquid does not change much as the pressure increases. 6. Calculate the fugacity of a liquid at high pressure using the Poynting correction. 7. Calculate fugacities for pure components from pressure and volume data at a given

Apply the equation for changes in Gibbs energy ( VdP dG ) at constant temperature to a pure fluid 10. Explain the criteria for single-component phase equilibrium in terms of fugacity. 11. Apply the concept of vapor pressure to predict behavior of single-component, two-phase systems when process parameters change. 12. Predict behavior of two-phase systems with two components where only one component can be present in the liquid phase (air/water systems) 13. Calculate heat of vaporization or vapor pressure at a given temperature from the Clapeyron equation and the Clausius-Clapeyron equation 14. Describe the behavior of fugacity as the ideal gas limit is approached....
