Abstract
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 is relatively small, so the liquid is entrained upward. The liquid flow is then directed downward into a large disengaging area. 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.
