Separation Processes II

Recommended Prerequisites

Calculus I and II, Linear Algebra and Analytic Geometry, Physics I, Physical Chemistry of Surfaces, Transport Phenomena I and III, and Separation Processes I.

Teaching Methods

The teaching is provided through lectures and theoretical-practical classes. In the lectures are exposed theoretical concepts and methodologies in the study of problems, together with some application examples. In theoretical practical classes the students must solve problems for applying concepts learned in the lectures. These classes are also designed to solve more complex problems related to the design of the equipment, in which the work and group discussion are promoted.

Learning Outcomes

Acquiring basic knowledge engineering for analyzing processes based upon the transfer of momentum and rate-controlled separations included in the curricular unit; apply the concepts related with the interaction solid/fluid in the interpretation of the mechanical separation mechanisms of solids by gravitational action and/or centrifuge; know the main membrane processes and be able to apply the models for predicting the flow; understand the basic principles of separation of components from a mixture by using adsorbents and ion exchange resins; be able to calculate equilibrium and mass transfer parameters from phenomenological models.

Acquisition of knowledge about calculation procedures for sizing and selection of equipment.

Develop the following skills: domain of theoretical knowledge, ability to integrate knowledge, ability to learn independently and apply theoretical concepts to new situations.
