Spec Sheet Description
Absorption and Stripping Pilot Plant
Mod. ADS/EV manual
Mod. ADSa/EV automated
This absorption and stripping system enables to study the mass transfer from a gaseous phase to a liquid phase (absorption) and vice versa (stripping).
The absorbing liquid is fed by a metering pump to the top of a column with glass Raschig rings packing.
The gaseous phase is the result of the mixture between the gas to be absorbed and a carrier gas; the flow rates of these two gases are measured by mass flowmeters.
The automated version (mod. ADSa/EV) includes a PID controller that controls the flow rates of gases automatically via two pneumatic valves.
Training Program:
- Checking the absorption degree with different liquid substances at different temperatures
- Desorption of liquid phase into gaseous phase with a gas
- Calculation of the number of theoretical stages
- Automatic flow control by PID controller (for mod. ADSa/EV, only)
- System supervision by P.C. (for mod. ADSa/EV, only)
- Absorption of NH3 with H2O
- Absorption of CO2 with solution of NaOH
- Stripping of NH3 with air
Supplied with Theoretical – Experiement Handbook
The equipment can be modified on request of the Customer.
