Abstract
Multiple downcomer trays having increased active area for vapor-liquid contact and separation are described. The increased active area of the tray is achieved by adding raised bubble promoters surrounded by perforated vertical contactors on the tray deck. The bubble promoters and surrounding vertical contactors are located under the downcomers from the tray above. The bubble promoter and surrounding vertical contactor promote uniform fluid flow and contact.
