Absorption Operations in Packed Column

Absorption operations in packed column

A packed column is a cylindrical vessel under pressure, filled with a suitable packing material between the internal section 1 and 2.

The liquid flows down by gravity through the surface of the packing elements forming a thin film layer around it. The gas rises in counter-current mode with the liquid stream.

The mass transfer takes place through the interface film present between the gas and the liquid.

The column is now a continuous differential contacting devices. There is no distinguishable stage (like the plates in a tray column) present anymore.
