Learning objectives
The student are required to learn the following knowledge:
Phase equilibria under non-ideal conditions;
Main separation techniques (fundamentals) and their integration in a process scheme;
Sizing and rating criteria for absorption/stripping columns, distillation columns and extraction (deepen);
Criteria for economical evaluation of process alternatives and for process intensification.
LABORATORY
The aim of the course is the education for the students in the practical use and management of unit operations in chemical plants, in particular for what concerns distillation and absorption columns.
Final competences will be the ability to size single unit operations, to evaluate their economic sustainability and integration in a given process.

LABORATORY
The acquired skills will be the practical use of the plants, the obtaining of numeral values, the numerical elaborations and the process simulation. The basic knowledge of the theory, the description of the plants and the numerical exercises will be discussed and presented during the lessons.

Course content
Finding thermodynamic data and mention to group contribution methods.
Applied thermodynamics: models for activity and fugacity coefficients.
Vapor-liquid equilibrium (VLE) in ideal and non ideal cases; thermodynamic consistency of VLE. VLE diagrams.
Liquid-liquid Equilibrium (LLE): diagrams for binary and ternary mixtures.
Absorption: unit operations for absorption and stripping. Columns and packings, sizing and rating of columns, pressure drop assessment. Absorption with stage columns, sizing.
Distillation, sizing and rating: flash, stage and packed columns, binary and multi-component mixtures. Discontinuous operations. Theoretical stages and efficiency models.
Liquid-liquid extraction: sizing and rating, partition and selectivity coefficients, choice of the solvent.
Criteria for the quantification of fixed and variable costs for separation processes.
Process intensification: examples.
Process simulation software: potential and limits, practical exercises.

Lectures and exercises will be mixed, to fix the main concepts. Exercises will be planned on licenced software for process simulation. This module is strictly correlated to the lab.

Course content [required]

1. Determination of a vapor pressure of a pure liquid
2. Obtaining of liquid vapor data for a binary mixture at constant pressure
3. Use of a continuous distillation column at finite and infinite reflux
4. Use of a continuous absorption column with different flowrates of liquid and gas

Assessment method
The students will work in groups. Each group will present a final report with all the results and elaborations that will be discussed in the final oral examination. The questions will concern the description of the plants, the experimental procedures, the numerical elaborations and the process simulation used in the lab.
