Objectives

Study of adsorption and membrane processes.

Learning outcomes and competences

The student should be able to design an adsorption or membrane process for a given separation.

Working method

Presencial

Program

i) Introduction. Separation processes: classification.
ii) Adsorption. Classification of adsorbents. Structure and new forms. Measurement and prediction of equilibrium. Measurement of difusivities. Batch adsorption. The batch adsorber as a dynamic system. Fixed bed adsorption. Propagation of concentration waves: de DeVault equation. Equilibrium theory: dispersive and compressive waves. Stationary fronts. The adsorption column as a dynamic system.
iii) Chromatography. Types and operating modes. HETP and the Van Deemter equation. Separation of proteins: perfusion.
iv) Ion exchange and electrophoresis.
v) Cyclic processes: pressure swing adsorption (PSA); 
simulated moving bed (SMB); temperature swing adsorption (TSA) and parametric pumping (PP).
vi) Membrane processes: basic concepts; modules. Gas Permeation; reverse osmosis; microfiltration, ultrafiltration and nanofiltration; electrodyalisis; pervaporation. Concentration polarization, gel formation and fouling.
viii) Selection and sequencing of separation processes.

Teaching methods and learning activities

Theoretical explanation of adsorption processes and mass transfer in membrane systems. Some real problems are treated in the practical lessons to encourage the students to solve new problems and to use a systematic approach.

Eligibility for exams

According to Faculty rules.

Calculation formula of final grade

FG= p1*FE + p2*T + p3*R;   

FG=Final Grade; FE=Final Exam; T=Test; R=report

p1= 0.65
p2= 0.20
p3= 0.15

Pass criterion: FG >= 9.5 and FE>=7.0

Recurso:

CF=FE

NOTE: The FE will consist of two parts. The minimum rating of FE>=7.0 will be applied proportionally to each of the parts.
