Abstract
The tray column ( ) has downcomers ( ) for transporting a liquid between adjacent trays ( ). The liquid transport takes place in each downcomer through a plurality of discharge apertures ( ) onto a loaded tray. Liquid flows out of the discharge apertures in the form of jets ( ) that blend into a regionally divergent flow field ( ) on striking the loaded tray. The flow field has transverse components of the flow speed with respect to a longitudinal main flow direction ( ). Guide elements ( ) are arranged beneath the discharge apertures and at a spacing from the loaded tray which each guide the impulse of liquid corresponding to the divergent flow field. The guide elements contribute to forming the transverse speed components such that the longitudinal component of the flow speed has a largely constant profile in each plane perpendicular to the main flow direction. The discharge apertures are preferably made in different sizes in a graduated fashion to be smaller in a central region than in adjacent flank regions.
