Solid-fluid separation
[MAPR2380]
[30h + 30h] 5 credits
This course is taught in the 1st semester.
Teacher(s): Pierre Adam, Denis Mignon
Language: English
Level: Second
Aims
Main themes
- Crystalline state, crystal lattice and polymorphism.
- Phase equilibrium.
- Crystallisation kinetics (seed formation and crystal growth).
- Practice and instrumentation.
- Industrial applications.
Theoretical fundamentals for the solid fluid separation techniques
- Physical properties of liquids and solids: porous media characterisation (particles size, shape and distribution, porosity); introduction to surface tension
- Fluid flow through porous media: model of Kozeny-Carman; laws of Kozeny, Burke-Plummer, Ergun; co-current two-phase flow
- Settling of particles thought fluids: laws of Sokes, Allen, Newton
Solid fluid separation techniques
- Sedimentation, centrifugation, cyclone, hydro cyclone
- Washing and deliquoring of cakes
- Filtration: sieving, cake filtration, clarification, deep bed filtration
- Membrane filtration: micro-, nano-, ultra-filtration, reverse osmosis, crossflow filtration, diafiltration
Content and teaching methods
The second part of the course is dedicated to the solid fluid separation techniques. Those techniques have been grouped in the four categories described here above. For each of them, the study will be done as follow:
- Description and phenomenological study
- Modelization and sizing
- Description of industrial equipments and main applications
Practical work sessions will illustrate those aspects.
