A tray column is a type of equipment used in separation processes, specifically for gas absorption and stripping, where the gas phase interacts with a liquid phase on multiple horizontal trays or plates. Each tray provides an area for mass transfer, allowing for efficient contact between the gas and liquid phases, which helps in removing or adding components to the gas stream. This design maximizes surface area and facilitates the movement of materials between the phases, enhancing the overall separation efficiency.
congrats on reading the definition of tray column. now let's actually learn it.
