Process Separations I

Recommended Prerequisites

Calculus I, II and III, Chemical Thermodynamics, Transport Phenomena I and II, Mass and energy balances, Applied Computing, English.

Teaching Methods

Theoretical (T) and theoretical-practical (TP) sessions. In the T sessions basic concepts and real situations are presented, as well as practical examples. Case studies and practical problems are discussed and solved by the student during the classes. Students are asked to solve some problems during the TP sessions, where discussion and working in group are encouraged. The independent study based on the use of the LABVIRTUAL platform is also stimulated.

Learning Outcomes

The student must be able to:

• Integrate the Chemical Engineering basics to design and dimension processes and equipment of transfer and separation.

• Design and dimension equipment for separation based on the mechanisms of mass transfer and on the equilibrium stage concept

• Understand  the similarities of the design strategies for the distinct separation processes

• Select the most suitable model for the design of a separation unit considering the feed stream characteristics.

• Criticize and discuss how changes in operating parameters, including the characteristics of the feed current, can influence the design of the separation equipments.

• Optimize the operation of the separation equipment

• Select the separation process and equipment best suited to each situation.

• Understand the need of combining in the same process different types of separation equipment.

• Evaluate equipment and industrial units

• Design more complex equipments.

Work Placement(s)
