PRINCIPLES OF CHEMICAL ENGINEERING 2
Mod. THERMODYNAMICS IN NON IDEAL SYSTEMS
Program of the course. 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.
Requirements. 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.
Typology of the activities. An oral exam and a discussion and evaluation of numerical exercises
performed independently by the student.
