The essential difference between distillationand absorption is ‘partial vaporization’ of theliquid.q

The ratio of the liquid to the gas flowrate isconsiderably greater in absorption.

esorption (or stripping) is the removal of a component from a liquid stream via vaporizationand uptake by an insoluble gas stream. ^
Thus, absorption and stripping are opposite unitoperations, and are often used together as a cycle. ^
Both absorption and stripping can be operated asequilibrium stage processes using trayed columnsor, more commonly, using packed columns.
