Adsorption Air Dryer

The Adsorptive Air Drying has been specifically designed to enable the complex theoretical principles of adsorption processes to be conveyed clearly and comprehensibly. Moist air flows through the adsorbent (silica gel), which is placed in a transparent column as a packed bed, and the moisture is adsorbed. The adsorbent contains an indicator. The colour of this indicator shows the position of the mass transfer zone. Once the capacity of the adsorbent in this column is exhausted, the moist air is fed through a second column with regenerated adsorbent. The experimental setup allows simultaneous investigation of the adsorption process and the regeneration process for the adsorbent which uses heated air. Recordings of all relevant parameters enable both processes to be completely balanced.
