Abstract
Method of and apparatus for imparting directional liquid flow on a chemical process tower tray. A series of raised tray areas are disposed about the tray surface for affecting preferential vapor flow therethrough. The raised tray regions are constructed with directional flow louvers for creating a directional vapor flow, which vapor flow imparts a directional flow vector to the liquid flowing thereacross. In this manner, regions of the tray which may be subject to stagnation from retrograde flow manifest directionalized flow for maximizing tray efficiency and vapor liquid interaction.
