A mass and heat transfer device uses a substantially vertical surface to separating a first fluid space (20a) from a second fluid space (90b) with the first fluid space (20a) containing a downward flowing liquid (22) in at least a partially flooded state and an upward flowing gas (34) contained at least partially within the downward flowing liquid (22). A fluid distribution surface (30) with one or more apertures (32) is provided within the first fluid space with the apertures (32) controlling the downward passage and distribution of the upward flowing gas (34). A heat transfer with fluid (22) in the first fluid space (20a). The fluid distribution surface (30) can be used in a horizontal, vertical or angled position and in annular, cylindrical, and hexahedral forms.
