A gas–liquid contactor is a particular chemical equipment used to realize the mass and heat transfer between a gas phase and a liquid phase. Gas–liquid contactors can be used in separation processes (e.g. distillation, absorption) or as gas–liquid reactors or to achieve both purposes within the same device (e.g. reactive distillation). == Typologies == They are divided into two main categories: * ''differential gas–liquid contactors'': the mass transfer happens within the entire length of the contactor〔 and the vapor–liquid equilibrium is not reached in any point of the equipment;〔 * ''stagewise gas–liquid contactors'': the vapor–liquid equilibrium is reached within each stage of the equipment and mass transfer happens in a part only of the volume of each stage. Examples of differential gas–liquid contactors are: * Falling-film column * packed column * bubble column * spray tower * gas–liquid agitated vessel. Examples of stagewise gas–liquid contactors are: * plate column * rotating disc contactor * Venturi tube.
