Heat transfer and real reactors


At the end of this module, the student will have understood and be able to explain (main concepts) :
- reactors with variable volume / flow rates
- notions of yield and specificity of multiple-reaction systems
- reactor combinations (series- parallel, recycle plug flow reactor)
- the mechanisms of mixing and their effect on the reaction
- influence of non-ideal conditions on the conversion: Residence Time Distribution
(notion of transfer function) and concentration distribution (mixing)
- the influence of temperature on the performance of a reactor, the notion of Optimal
Temperature Progression
- general equation for energy conservation
- heat transfer phenomena (steady and unsteady state):
- conduction (Fourier's law)
- convection (forced and natural)
- radiation heat transfer
The student will be able to:
- calculate ideal open reactors for variable flow conditions
- calculate the size or yield or selectivity of ideal open reactors for multiple
reaction systems and the conversion obtained through reactor combinations
- determine the RTD of a reactor
- apply a model for mixing or for mass flow to predict the conversion for a non-uniform
- calculate the OTP for a given system
- establish and solve energy balances on systems with or without reactions
- calculate heat losses through lagging (critical thickness of lagging)
- characterize heat transfer in fins
- determine the temperature gradient in a catalytic reactor and a single-phase

Needed prerequisite

Transport phenomena and reactions in fluids
Engineering thermodynamics

Form of assessment

The evaluation of outcome prior learning is made as a continuous training during the semester. According ot the teaching, the assessment will be different: as a written exam, an oral exam, a record, a written report, peers review...
