Background

Stripping is a unit operation used to recover absorbed solutes and to separate the absorbent from the solutes for regeneration. Meanwhile, in some cases, the stripping is also used for removing light components in liquid, such as the oil refining industry which uses steam as a stripping agent to remove the light components of oil varieties. Stripping can be used in conjunction with absorption or alone.

The stripping column may be in the form of a tray column or a packed column. In any form of tower, raw materials enter the tower from the top of the tower and leave the tower from the bottom of the tower; the desorbent enters the column from the bottom of the column, contacts the liquid feed in countercurrent in the column, and leaves the column at the top of the column along with the components being stripped. In contrast to the absorption column, the concentrated end is at the top of the column and the dilute end is at the bottom of the column, the equilibrium partial pressure of the solute in the liquid phase in the stripping column is greater than the partial pressure of the solute in the gas phase, and during the stripping process, the solute molecules need to be phase-changed into gas, which is an endothermic process, so the temperature of the stripping agent is generally equal to or greater than the temperature of the raw material, otherwise the stripping effect will be reduced.
