PILOTADS  010

Continuously operating system for studying the adsorption process.
The system is designed for training students in process engineering / thermodynamics in universities.

The adsorption process can be shown with a mixture "wet air/dry air" or "Air/CO2 and active carbon or molecular sieve as adsorption material. The regeneration is performed by heating up the adsorption material combined with air stripping.

An operating and tutor manual describing the adsorption theory and practice are included and will be delivered with the system.



ADSORPTION
A special vessel is used for loading the air with water for getting wet air. The wet air can be combined with dry air and the start concentration C0 (wet air = air loaded with water)
can be measured at the adsorber inlet by hygrometer.

The adsorption process takes place in the adsorption tower, i.e. the moisture is adsorbed at the adsorbans. The concentration C (wet air) can be measured at the adsorber outlet by the hygrometer. The breakdown curve (concentration vs. time) has to be determined for various loadings.

The  extension  "CO2“ - operation enables to perform the adsorption process with a CO2 / air - gas mixture.

The following features are to be tested in experimental works:

1.    Testing of several adsorbans, e.g. activated carbon, etc.
       standard adsorbans, e.g. molecular sieve 4/5 A°

2.    Determination of breakdown curves for isothermal adsorption lines at                     constant temperature for various loadings

3.     Breaking - through point is the outlet concentration range of 5 % inital                       concentration to 95 % (saturation point)

4.    Determination of  isothermal adsorption lines from the breakdown curves.
       a)    graphically
       b)    correlated to equations of Freundlich, Langmuir and Brunauer, Emmet,                  Teller (BET-equation)

5.    Determination of activity by various evaluation methods

6.    Calculation of mass transfer zone “MTZ“ and determination of  height of                   mass transfer zone “HTZ“
