Abstract
A contact tray for use in a mass transfer or heat exchange column and having a tray deck with an inlet area and a remotely positioned outlet for respectively receiving liquid on the tray deck and then removing the liquid after it has flowed across the tray deck and interacted with another fluid on and above the tray deck. A plurality of barriers are positioned between the inlet area and the outlet. The barriers each have spaced-apart pickets and openings in the spacing between adjacent ones of the pickets. The pickets impede the flow of the liquid and increase the upstream liquid loading on the tray deck as the liquid flows from the inlet area, through the openings, and then into the outlet. At low liquid flow rates, this increase in the liquid loading may significantly increase the vapor handling capacity of the tray.
