AIMS AND CONTENT

LEARNING OUTCOMES

To study the thermodynamics of open or variable-composition systems with reference to the specifics of ideal systems.

LEARNING OUTCOMES (FURTHER INFO)

To study the thermodynamics of open or variable-composition systems with reference to the specifics of ideal systems. In particular, the course will furnish the means of determining thermodynamic properties, beginning with volumetric data, and calculating the chemical equilibrium among phases and in reacting systems to be utilised in the study of process engineering systems.

TEACHING METHODS

Organisation. The course consists of about 35 hours of lessons and 25 hours of practical work conducted in the classroom.

SYLLABUS/CONTENT

Program. First and second laws of thermodynamics (summary). Thermodynamic functions and chemical potential. Gibbs Duhem equation. Molar, partial molar and mixing properties.

Phase and reaction equilibrium criteria in terms of extensive and intensive properties. The phase rule. Ideal solutions. Phase equilibrium for a pure component and for ideal binary systems. Subcritical and supercritical components: Raoult and Henry laws. Some numerical examples. Phase equilibrium diagrams for ideal binary systems and their deviations. Ternary equilibrium diagrams (outline)

Equilibrium in reacting systems. Thermodynamic properties for ideal systems. Some numerical examples.

Isothermal and adiabatic flash for binary and multicomponent systems. Continuous distillation for binary systems. MacCabe Thiele method. Stage and column efficiency.
