OVERVIEW

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.

AIMS AND CONTENT

LEARNING OUTCOMES

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.

AIMS AND LEARNING OUTCOMES

The case study in the computer laboratory is carried out in group, and allows to improve transversal skills such as communication skills and ability to work in a team. The case study is an important element in the preparation for the exam.

TEACHING METHODS

The course consists of lectures (50 hours) and classes in the computer lab (10 hours).

SYLLABUS/CONTENT

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.

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.    

The theory is developed in parallel with exercises. In particular, a distillation problem is solved with UniSim (process simulation software) in the computer classroom.

EXAMS

EXAM DESCRIPTION

The exam is written-oral: the teacher assigns some questions, typical of an oral exam, to be answered and discussed in writing.

ASSESSMENT METHODS

The exam is written-oral: the teacher assigns some questions, typical of an oral exam, to be answered and discussed in writing. The questions are related to the various types of separation columns. The student must demonstrate that she/he has acquired design skills using traditional graphic methods, and that she/he is familiar with the calculation methods implemented by modern simulation softwares. The student must also demonstrate that she/he has acquired management skills for pre-existing columns.
