Subject Description

The objective of this unit is to present the fundamentals of thermodynamics and their applications in chemical engineering. Topics covered include:

Energy conservation and the First Law, internal energy U. Application of the First Law to flow processes and enthalpy H. The Second Law and reversible processes. Carnot cycle, thermodynamic efficiency and entropy S. Combined First Law and Second Law, Gibbs and Helmholtz functions. Thermodynamic identities and the Maxwell relations. Conditions of equilibrium. P-V-T diagrams of pure substances, ideal gas and departure from ideality, equations of state, fugacity. Calculations of thermodynamic properties and thermodynamic charts. Isentropic expansion in nozzles and nozzle efficiency, vapour and gas power cycles, compressors and expanders, turbines, refrigeration and gas liquefaction. Availability and use of availability in the analysis of processes. Partial molar quantities, chemical potential and activity coefficient, gas mixtures and liquid mixtures, dilute solution. Solubility of a gas in a liquid and a solid in a liquid. The phase rule, phase equilibria in one component systems, two·component systems (vapour-liquid, liquid-liquid and solid-liquid systems) and three-component systems.

Assessment
