Academic Year 2021/2022

Free text for the University

Objectives

Knowledge and understanding:
- Fundamental thermodynamics concepts: extensive and intensive physical quantities, molars, specific, and volume properties; transport and transformation phenomena; balance equation; equilibrium state; phase equilibrium; chemical balance;
Applying knowledge and understanding:
Ability to use the acquired knowledge to analyze and solve (analytically, numerically, or graphically) problems of chemical engineering. Specifically:
- Calculation of the thermodynamic properties (internal energy, entropy, enthalpy, Gibbs free energy, Helmholtz free energy) of unary and binary systems with ideal and non-ideal behavior;
- Applications of internal energy balance equation (first law of thermodynamics) to simple systems;
- Applications of entropy balance equation (the second law of thermodynamics) to simple systems;
- Reading and interpretation of a unary phase diagram;
- Reading and interpretation of a binary phase diagram;
- Calculation of phase equilibria in unary systems;
- Calculation of the liquid-vapor phase equilibrium of binary systems;
- Calculation of the chemical equilibrium in the case of a single chemical reaction with a number of chemical species less than or equal to three.
The following skills will be also pursued:
- Thermodynamic analysis and characterization of simple systems;
- Identification of important phenomena and parameters from the thermodynamic point of view;
- Identification and selection of suitable simplifying assumptions in thermodynamic analysis;

Prerequisites

It is required a basic knowledge of mathematics, chemistry and physics.

Teaching Methods

The course is divided into lessons and exercises for a total of 90 hours. The course covers lectures and classroom exercises. Excel- or Opencalc-based procedures for thermodynamic calculations are routinely adopted.

Teaching will be performed mainly in presence, integrated and "augmented" with online strategies, in order to guarantee its use in an innovative and inclusive way.

Verification of learning

The exam consists of personalized exercises to be carried out independently, which must be delivered by the official of the exam. The exam is completed by a written test consisting of multiple choice or free response questions.
The purpose of the exercise is to assess the applying knowledge and understanding of the student. The assessment of knowledge and understanding is instead the aim of the written test.
