Hydrodynamics of Packed Bed
This reduction in porosity decreases the gas velocity, increases the pressure drop and changes the value of mass transfer co-efficient. It is a packed column packed with Raschig Rings where the Air is counter currently fed to column. The water is fed from the top of the column and loading & flooding characteristic are observed on various flow rates of Air and Water. Liquid holdup in the column increases the weight of column and also reduces the effective porosity of packing.
