Description
Chemical engineering refers especially to chemical reaction engineering. Indeed, chemical reaction, catalyzed or not, are at the heart of all industrial syntheses. Study of a chemical reaction, in a perfectly‐stirred reactor, permits the operator to understand the influence of the different parameters in the optimization of the chemical synthesis with a view to its industrialization.
Features:
- Study and compare four continuous reactors from two different experiments:
- Monitoring the dispersion (NaCl) in water to determine the residence time
- The saponification of ethyl acetate by soda
- Contains four different reactors with the same volume (0.8L):
- One perfectly stirred reactor
- A cascade of two perfectly stirred reactors
- One plug-flow reactor
- One tubular reactor
- Hydrodynamic study of the reactors by the residence time distribution (RTD) method:
- Determine residence times
- Compare theoretical and experimental results
- Determine the chemical conversion rate by conductivity measurement:
- Materials balance, reaction yield
- Compare the efficiency of the different reactors
Proposed Experiments:
- Determine the residence time distribution (RTD):
- Inject a coloured tracer and monitor conductivity.
- Use the experimental conductivity = f (time) graphs to determine the residence time for each reactor.
- Compare the reactors.
- Saponification of ethyl acetate with sodium hydroxide.
- Calibration of conductivity sensors for sodium hydroxide assay.
- Monitor the reaction conductivity and determine the sodium hydroxide conversion rate.
