The course is focused on separations columns, and in particular columns for distillation, absorption and liquid-liquid extraction. Thermodynamics is recalled briefly, and then the main equations are derived on a theoretical basis. Graphical tools are illustrated as well, with attention to the underlying simplifying hypotheses. The theory is developed in parallel with exercises. In particular, a distillation problem is solved with UniSim (process simulation software) in the computer classroom.
Separation columns: design capability through the use of one the most modern software (UniSim). Capacity of management of pre-existing columns. Optimization of operating parameters of pre-existing columns.
The course consists of lectures (50 hours) and classes in the computer lab (10 hours).

Thermodynamics is recalled briefly, and then the main equations are derived on a theoretical basis. Graphical tools are illustrated as well, with attention to the underlying simplifying hypotheses.
Columns are classified as plate or packed columns. The specific features of each type of column is discussed in terms of costs and suitability to specific operating conditions. Design features are discussed (type of trays, types of packing materials), together with fluid dynamic problems (loading, flooding, weeping, etc). Efficiency (Murphree, Hausen, column) is discussed. Cost issues are discussed as well.

First semester (start of class: September 20th).
The exam is oral-written.
In the oral-written exam, the teacher asks a number of questions, and the students are asked to anwer in written form.
