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 Gas permeation Reverse osmosis Microfiltration, ultrafiltration and nanofiltration Electrodialysis Pervaporation Concentration polarization Gel and fouling formation Crystallization Crystallization from solutions; Types of equipment; equilibrium analysis; phase equilibrium; fractional crystallization; nucleation and crystal growth; Balance of distribution and size of crystals; melt crystallization Hybrid processes PSA/membranes SMB/crystallization Selection and sequence of separation processes

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.
