Chapter 5 Absorption and Stripping

2011-3-14  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.
