Absorption in Packed Bed


The set up consists of three glass column packed with different packings, feed tank, CO2 cylinder with regulator, air regulator with pressure gauge, rotameter, receiving tray and piping. Metered quantity of fluid is distributed over the packing while metered gas and airflow is passed through the bed vertically upwards. The gas air mixture is absorbed in the liquid. All the flow rates can be independently varied to simulate different conditions and by measuring the concentration of gas absorbed in the liquid the overall volumetric mass transfer coefficients can be calculated.


  • To determine the number of transfer units, height of transfer unit, and overall mass transfer coefficient for the three columns. 
  • To demonstrate the difference in mass transfer coefficients for the three different types of packing.


  • Continuous operation
  • Superb Painted structure
  • Simple to operate & maintain
  • Compact &stand-alone set up
