Separation Processes II (Option)
Chemical and Biochemical Engineering, Publication in the Diário da República - Despacho nº 10764/2011 - 30/08/2011
5.5 ECTS; 3º Ano, 2º Semestre, 30,0 T + 30,0 P
Prior knowledge of fluid mechanics and mass and energy balances.
Students must be able to determine the basic equipment design parameters in particles/droplets separation processes from fluids (classification, centrifugation, sedimentation and filtration). They must be able to evaluate the hydrodynamic effects of the fluid flow through particle beds.
1. MECHANICAL ANALISIS OF A MOVING PARTICLE IN A FLUID
Terminal Velocity and Stokes law. Gravitational classification of solid particles.
2. FLOW AND SEPARATION OPERATIONS OF PARTICLES AND DROPLETS
2.1 - Centrifugation
2.2 - Sedimentation
2,3 - Fixed beds
2.4 - Fluidized beds
2.5 - Relationship between the different flow regimes of fluid-solid
2.6 - Filtration
Assessment includes written tests (continuous assessment or exams) and involves theoretical and practical questions involving the design of equipment.
