PIGNAT Continuous Reactors - RAP2000

PIGNAT Continuous Reactors – RAP2000

PIGNAT

Product Code: RAP2000

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.
