3. Efficiency of cross-current trays
3.1 Efficiency definitions
Trays are designed to transfer matter and heat between a liquid and a gas phase. A theoretical tray is one whose outlet streams are made up of a liquid phase and a gaseous phase in equilibrium with each other.
SCROLL TO TOPThe overall efficiency η0 of a column is the ratio of the number of theoretical trays (NPT ) required to achieve the separation obtained to the number of trays actually existing in the column (NPR ) :
