Absorption / Desorption Unit

Absorption is a mass transfer process where a compound present in a gas phase is transferred to a liquid phase by dissolution. The reverse operation, transferring a dissolved gas using an inert gas, is called desorption. Learning Objectives: Study of column hydrodynamics.

These processes are carried out in a packed column between an ascending gas effluent and a descending solution or solvent (counter-current operation). The packing increases the liquid–gas exchange surface area and thus mass transfer.
