Objectives

Adsorption processes and membrane technology.

Program

• Separation processes: classification; Percolation processes
• Adsorption processes

- Adsorption
Classification of adsorbents; Structure: homogeneous, porous, bidisperse; new forms of adsorbents
Equilibrium measurement and prediction; diffusivity measurement in adsorbent systems;
Batch adsorption; Equilibrium and operation line
Analogy: batch adsorbent as a dynamic system
Adsorption in packed beds
Industrial processes
Propagation of concentration waves: De Vault
Equilibrium theory: dispersion and compression
Stationary front
Adsorption column as a dynamic system


- Chromatography
Types: GC, HPLC; Operation modes: elution, frontal, displacement
HETP and Van Deemter’s equation
Protein separation; Perfusion

Ionic permutation; Electrophoresis

Cyclic processes:
Pressure swing adsorption (PSA)
Simulated moving bed (SMB)
Temperature swing adsorption (TSA) and parametric pumping (PP)

- Membrane processes
Basic concepts; Modules

Teaching methods and learning activities

Theoretical explanation to provide the methodology to analyse dynamic systems and the analogy between different systems. Some real problems are treated in the practical lessons to encourage the students to solve new problems and to use a systematic approach.
