A fluid separation packing for distillation and fractionation columns or towers comprises a number of connected packing elements, suitably in the form of connected octagons, which have continuous side walls (16) with an upper end and a lower end which terminates in a base (14) with a vapor opening and a vapor tab (18) above the opening. The side walls define openings between adjacent packing elements and are connected to one another to define a contacting volume above the base, and there are liquid exit slits (34) on the side walls into downcomers which have side walls with their upper portions within the openings between adjacent packing elements, with openings in the lower portions of the downcomers supplying liquid into underlying packing elements.
