Absorption Columns and Trickle Beds An absorption column is a packed column with a gas inlet at the bottom and a liquid inlet at the top. The countercurrent flow of the two fluids allows for the mass transfer operation known as absorption, where a component of the gas mixture is transferred to the liquid phase in which it is soluble [1].
