A plate column (or tray column[1]) is equipment used in chemistry to carry out unit operations where it is necessary to transfer mass between a liquid phase and a gas phase. In other words, it is a particular gas-liquid contactor.[2] The peculiarity of this gas-liquid contactor is that the gas comes in contact with liquid through different stages;[1] each stage is delimited by two plates (except the stages at the top and bottom of the column).
Some common applications of plate columns are distillation, gas-liquid absorption and liquid-liquid extraction. In general, plate columns are suitable for both continuous and batch operations.
