Adsorptive Air Drying

Continuous adsorptive air drying
2 compressors to deliver the feed air and regenerative air out of the ambient atmosphere
Humidification of the feed air by flowing through a water bath
Adjustment of regenerative air and feed air flow rates by valves
2 columns for alternating charging and regeneration of the adsorbent
Adjustment of relative humidity and temperature of feed air by heater
Heater for temperature adjustment of the regenerative air
Observation of mass transfer zone by using transparent columns and adsorbent with indicator
Circular system with pump and refrigeration system to adjust the water bath temperature.
