The present invention pertains to multiple downcomer tray assemblies for chemical process columns.More particularly,one aspect of the invention includes a multiple downcomer tray assembly for a process column of the type wherein liquid flows downwardly from a first tray through first downcomers onto a second tray and across the active area or areas thereof.Across these active tray areas vapor flows upwardly for interaction and mass transfer with the liquid.The liquid then passes from the trays through downcomers.The present invention permits the downcomers of the first and second trays to be oriented generally parallel one to the other with a plurality thereof supported by baffles extending therealong.The baffles are connected to the downcomers by a plurality of angulated support members secured at one end to the baffle and at a second end to the tray-downcomer region.The trays are further supported by a tower support ring extending circumferentially therearound.
