The image under present the path of vapour and liquid circulate throughout a tray, and across a column. Packed columns are referred to as continuous-contact columns while trayed columns are called staged-contact columns due to the manner by which vapour and liquid are contacted. Vapour rises through the chimney and is directed downward by the cap, finally discharging through slots in the cap, and eventually bubbling via the liquid on the tray.
Types of Trays in Distillation Columns
The function of a tray is to combine the vapor and liquid together to kind a foam. The fluid on the tray is a mixture of vapor and liquid in the type of froth or foam. If the froth cannot drain rapidly from a downcomer onto the tray beneath, then the foamy liquid will back up onto the tray above. Vapors bubble up through the tray sieve holes, the place the vapor comes into intimate contact with the liquid. We ship all our trucks globally, so there isn't any location too far for us. Where $\sigma$ is surface tension of liquid (N/m) and g is gravitational fixed (m/s2).
