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 Murphree Efficiency of Absorption Column ?

It is quite reasonable to assume that the gases leaving the dispersion at different locations of a tray get mixed up before entering the upper tray. The concentration of the liquid on the tray changes as it flows over the tray. So an average liquid leaving concentration can be used to define the tray efficiency, known as the murphree efficiency. The Murphree plate efficiency is expressed as the ratio of the increase in mole fraction of solute in the gas phase passing through a plate in a column to the increase when the vapor is in equilibrium with the liquid.
