ADS Absorption And Stripping Pilot Plant Vocational Education Equipment for School Lab Chemical Engineering
This absorption and stripping system enables to study the mass transfer from a gaseous phase to a liquid phase (absorption) and vice versa (stripping).
TRAINING PROGRAM
This unit enables to deepen the following issues:
- Checking the absorption degree with different liquidsubstances at different temperatures
- Desorption of liquid phase into gaseous phase with a gas
- Calculation of the number of theoretical stages
- Absorption of NH3 with H2O
- Absorption of CO2 with solution of NaOH
- Stripping of NH3 with air
