Absorption and Stripping Pilot Plant (Large Line)

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 includes a PID controller that controls the flow rates of gases automatically

via two pneumatic valves.

TRAINING PROGRAM

This unit enables to deepen the following issues:

• 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

• System supervision by P.C.

• Absorption of NH3 with H2O

• Absorption of CO2 with solution of NaOH

• Stripping of NH3 with air
