Objectives

The main purpose of Separation Processes II 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.

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.

4. Selection and sequencing of separations; Overview of separation methods; Energy, heuristics and environmental criteria
