Chapter 5 Absorption and Stripping
5-1 Chapter 5 Absorption and Stripping Introduction In Absorption (also called gas Absorption , gas scrubbing, or gas washing), there is a transfer of one or more species from the gas phase to a liquid solvent. The species transferred to the liquid phase are referred to as solutes or absorbate. Absorption involves no change in the chemical species present in the system. Absorption is used to separate gas mixtures, remove impurities, or recover valuable chemicals. The operation of removing the absorbed solute from the solvent is called Stripping . Absorbers are normally used with strippers to permit regeneration (or recovery) and recycling of the absorbent. Since Stripping is not perfect, absorbent recycled to the absorber contains species present in the vapor entering the absorber.
