Advanced Separation Processes

Objectives

The main purpose of Advanced Separation Processes is to provide to students the ability to:

- Understand the fundamental concepts of most recent separation processes in the chemical industry: crystallization, adsorption and chromatography and membrane separation processes.

- To design the equipment required for each of the studied processes.

Teaching method

The teaching comprises lectures and practical/laboratorial classes. Lectures cover all the content according with the syllabus. Wherever necessary example problems will be solved to illustrate the given concepts. Laboratorial classes are programmed to carry out practical works related to the lectures. The students will prepare and present a work related with the topics of the course, giving emphasis to new techniques of separation.

Evaluation method

Assessment:


1. Three mini tests (closed-booked), each one worth 20% of the final grade.
2. A mini project (to be held in a group including elaboration and presentation. It accounts for 20% of the final grade.
3. Laboratory team work, including elaboration and discussion of respective reports. It accounts for 20% of the final grade.

Subject matter

1. Crystallization; Solubility diagrams; Fractional crystallization with temperature swings; Nucleation and crystal growth; Population balances and crystal size distributions; Equipment.

2. Sorption and Chromatography; Adsorbents; Adsorption equilibrium; Solute movement theory; Local equilibrium theory; Packed bed adsorption; Mass transfer zone approach; Types of chromatography; Application of solute movement theory; Linear dispersion and staged models; Van Deemter equation and Rosen’s solution; Large scale chromatography.

3. Membrane Separations; Basic concepts; Membrane preparation and characterization; Modules; Transport in porous membranes: concentration polarization; Transport in nonporous membranes: solution-diffusion model; Membrane separation processes: pressure and concentration driven; Modules/configurations and applications.
