Absorption In Wetted Wall Column
The set up consists of glass column, feed tank, CO2 cylinder with regulator, air regulator with pressure gauge, Rotameter, receiving tray and piping. Metered quantity of fluid is distributed along with the walls of column from the top 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.
