Description

The full apparatus includes 6 chemical reactors (a continuous stirred-tank reactor CSTR, two plug flow reactors PFR, a batch reactor BR, 3 reactors in series and a laminator flow reactor LFR), interchangeable on the same service unit) and a supervision software with interface. The minimum purchasable configuration is represented by the service unit and by one of these reactors. The service unit  includes feeding tanks, feeding pumps, temperature control system and various instruments for the CSTR, for the plug flow reactor , for the batch reactor, for the CSTRs in series, for the plug flow reactor and for the laminator flow reactor. The reaction proposed is the classical saponification of ethyl acetate with sodium hydroxide, checked in real time with a conductivity meter.

TRAINING PROGRAM
This unit enables to deepen the following issues:
• Comparing CSTR, PFR, LFR and BR
• Variation of the conversion with the residence time
• Kinetic equation from experimental data
• Effect of temperature on reaction rate
• Effect of mixing degree on the reaction
