Credits: 6 |
Level: Intermediate |
Semester: 1 |
Assessment: EX80CW20 |
Requisites: |
Aims: To complete the teaching of core chemical engineering thermodynamics started in year 1.
Learning Outcomes: After successfully completing this unit students should be able to: * Understand the significance of and the means for estimating K values; * Estimate physical properties of pure components and mixtures (with the aid of reference material); * Question the validity of techniques used to estimate thermodynamic/physical properties, especially when using computer packages; * Apply the laws of thermodynamics to solve problems of power cycles and refrigeration. Skills: Analysis and problem solving (taught/facilitated and assessed). Content: * Prediction of physical properties and non-ideal vapour-liquid equilibria; * Determination of K values; * PVT relations, equations of state: Van der Waals, Redlich-Kwong, Benedict-Webb-Rubin and Virial equations, compressibility factor, Pitzer's correlation; * Mixture combination rules; heat capacity of gases and liquids, enthalpy and entropy as a function of temperature and pressure; standard heat of reaction, Maxwell's relations; * Chemical potential, Gibbs-Duhem equation; fugacity, fugacity coefficient and fugacity in a mixture; activity coefficient in liquid phase; excess thermodynamic functions, extension of binary experimental data to multi-component systems; * Combustion engines; steam and gas turbine power plant; refrigerators and heat pumps; compressors and expanders; nozzles and diffusers. |
