Difference between absorption and striping

Absorption and stripping are two different processes used in chemical engineering for separating components of a mixture.

Absorption is a process in which a gas is dissolved in a liquid. It involves the transfer of a gaseous component from the gas phase to the liquid phase. In absorption, the liquid phase is called the absorbent or solvent, and it selectively absorbs the desired gas component while the other components pass through. The driving force for absorption is the concentration gradient between the gas phase and the liquid phase. The absorbed gas is then removed from the liquid phase by a subsequent process, such as distillation or evaporation.

Stripping, on the other hand, is a process in which a liquid is used to remove a volatile component from a gas. It involves the transfer of a volatile component from the gas phase to the liquid phase. In stripping, the gas phase is called the feed gas, and the liquid phase is called the stripping liquid or solvent. The volatile component in the feed gas is selectively absorbed by the stripping liquid, and the non-volatile components pass through. The driving force for stripping is the concentration gradient between the gas phase and the liquid phase. The stripped component is then removed from the stripping liquid by a subsequent process,
