Formative aims: To study the thermodynamics of open or variable-composition systems with reference to the specifics of non ideal systems.
Formative aims: To study the thermodynamics of open or variable-composition systems with reference to the specifics of non 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 effective process engineering systems.
Didactic works: The course consists of about 35 hours of lessons and 25 hours of practical work conducted in the classroom.
Main contents: Fugacity in gas and liquid mixtures. Excess properties and activity coefficients. Estimate of activity coefficients for binary and multicomponent systems. Duhem Margules equation. Tests for thermodynamic consistency. Fugacity coefficients for pure component and in mixture. State equations. The law of corresponding states: two and three parameter equations. Thermodynamic properties from volumetric data. Estimation of fugacity coefficient. Departure functions. Some numerical examples. Fluid phase equilibrium in non-ideal binary and multicomponent systems. Some numerical examples. Reaction equilibrium for non-ideal systems.

Second semester of academic year
Examination procedure: An oral exam and a discussion and evaluation of numerical exercises performed independently by the student.
Technical skill: Formulation of phase equilibrium problems for non ideal binary or multicomponent systems. Determination of the thermodynamic properties of non ideal pure or mixed components. Calculation of the equilibrium reactions performed at medium or high pressure.
Prerequisites: It is anticipated that students will have a solid grounding in mathematics, chemistry, physics, thermodynamics of ideal system to be able to deal with the subject matter, but no formal prerequisite is required.
