Learning outcomes

The aim of the course is to provide the learner with detailed knowledge of the theory and methods needed to understand and design the more important unit operation used in the the chemical and process industry.

Course contents

Skills required to access the course

The course is delivered in italian and an excellent knowledge of Italian language (suggested level: C1) is required to access the course. No exceptions are possible.

In order to attent the course, knowledge of thermodynamics (multiphase and multicomponent gas-liquid, liquid-liquid and solid-liquid equilibria), fluid dynamics, transport phenomena (heat and mass transfer) are required. 

Course Contents

1) Introduction to unit operations.

2) Heat transfer in the absence of phase changes: theory, specific energy balances, introduction to equipment

3) Heat transfer during condensation and evaporation: theory, specific mass and energy balances, specific heat transfer coefficients, introduction to equipment.

4) Distillation: theory, specific mass and energy balances, calculation of theoretical stages, introduction to equipment.

5) Absorption and stripping: theory, specific mass and energy balances, calculation of theoretical stages, transfer units, introduction to equipment.

6) Liquid-liquid extraction: theory, specific mass and energy balances, calculation of theoretical stages, introduction to equipment.

7) Leaching: theory, specific mass and energy balances, introduction to equipment.
