What is Absorption Operation ?

Absorption is a physical separation process where one or more components are removed from a gas/vapor stream by a liquid stream. In industrial applications the liquid and vapor streams can have co-current or countercurrent flows. Absorption is usually carried out in either a packed or trayed column. The variables and design considerations for Absorbers are many. Among them are the entering conditions, the degree of recovery of the solute needed, the choice of the Absorbing agent and its flow, the operating conditions, the number of stages, the heat effects, and the type and size of the equipment.

What is Efficiency of Absorption Column ?

The contact between the phases on a tray is not uniformly good at all locations, i.e. the tray efficiency varies from one location to another. So Point efficiency is the ratio of actual enrichment of the gas to the maximum enrichment possible for the exiting gas if it reaches equilibrium with the local liquid.
If we assume the gases leaving the tray at different locations get mixed up before entering the upper tray. By using an average liquid leaving concentration we could define the murphree efficiency. The Murphree efficiency is the ratio of the increase in mole fraction of solute in the gas phase to the increase when the vapor is in equilibrium with the liquid.
The Overall Tray Efficiency can be used to calculate the number of real trays required for absorption. If (i) the gas, liquid flow rates and the equilibrium parameter m remain constant over a section of the column, and (ii) the Murphree efficiency remains the same for all trays, the relation between Murphree and Overall Efficiency can be derived.
