- Definition chemical equipment used to carry out unit operations (a basic step in a process) where it is necessary to transfer mass between a liquid phase and a gas phase, it is therefore a particular gas-liquid contactor (it realizes the mass and heat transfer between a gas phase and a liquid phase), in which the gas comes in contact with liquid through different stages, each stage being delimited by two plates (except the stage at the top of the column and the stage at the bottom of the column) Reference "COM-Terminology Coordination, based on:Wikipedia. Plate column, https://en.wikipedia.org/wiki/Plate_column [7.6.2017]"
- Comment "Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation.See also:- tray [ IATE:1166869 ] Do not confuse with plate scrubber [ IATE:1704848 ], for which some authors mistakenly use 'plate column'."
