This concept concerns a vapor/liquid-contacting tray which is useful in distillation and related mass transfer or heat transfer applications where liquid flows down and gas or vapor flows up through a vessel. In this device, the perforated area (3) is relatively small, so the liquid is entrained upward. The liquid flow is then directed downward into a large disengaging area (5). The downward momentum of the liquid and the large disengaging allow for high liquid and vapor rates without overloading the vapor/liquid disengaging capacity of the device.

L'invention concerne un plateau permettant de mettre en contact une vapeur et un liquide. Ce plateau est utile pour la distillation et les applications connexes de transfert de chaleur et de transfert de masse, où le liquide descend et le gaz ou la vapeur monte à travers un récipient. Dans le présent dispositif, la surface perforée (3) est relativement réduite, de sorte que le liquide est entraîné vers le haut. Le courant liquide est ensuite dirigé vers le bas dans une grande zone de séparation (5). La force d'impulsion vers le bas du liquide et la grande zone de séparation permettent de traiter des courants de liquide et de vapeur à débit élevé sans pour autant surcharger la capacité de séparation vapeur/liquide du dispositif.
