Project in Unit Operations

Code 8857
Year 3
Semester S2
ECTS Credits 6
Workload TP(60H)
Scientific area Industrial Chemistry
Entry requirements Not applicable.
Mode of delivery Conceptual teaching applied to theoretical problem solving, experimental work and unit operations design.
Work placements No training in industrial environment, but with possible interaction with industrial units during the unit operations project implementation.
Learning outcomes Students should acquire the basic knowledge about mass transfer, fluid mechanics and heat transfer in order to understand and design unit operations; the student should be able to identify the transport phenomena in unit operations and in the chemical and biochemical manufacturing processes. The students should be able to use this basic knowledge to understand the experimental work carried out. The students should be able to solve problems on the concepts learned and be able to project not complex unit
operations.
Syllabus Theoretical
1. Introduction to mass transfer (mechanisms, individual resistances, resistances in series; individual and overall coefficients ; empirical equations )
2 . Introduction to heat transfer (mechanisms, individual and global resistances)
3 . Fundamentals of adsorption
4 . Basics of filtration
6 . Fluids
6.1 Hydrostatic
6.2 Fluid dynamics (Bernoulli's equation, laminar and turbulent flows, calculation of losses; sizing centrifugal pumps, performance curves and NPSH)
6.3 Fluid rheology
7 . Power production and refrigeration
Practical work:
1. Diffusion coefficient in gaseous phase.
2 . Absorption of oxygen in water
3 . Adsorption isotherms
4 . Heat transfer coefficients for the natural and forced convection around a cylinder
5 . Overall heat transfer coefficients in coils
6 . Filtration of CaCO3 and pulp suspensions
Component of the project:
Preliminary design of a unit operation.
