Valve Tray

Tray columns are used for making contact between a gas phase and a liquid phase so as to bring them as close as possible to the equilibrium state. Tray columns are widely used in various types of mass transfer operations. All the simulation results, which predict a certain number of theoretical stages, can be converted to actual trays depending upon tray efficiency for a particular service. In any conventional tray vapor rises through the liquid pool on the tray deck and then disengages from the liquid in the space above the deck. Liquid enters the tray from a downcomer above and leaves via a downcomer below.
