ABSTRACT:
A baffle system for use on a plate for mass transfer operations comprises at least one channel, the surface of the channel through which a two-phase mixture of liquid and vapor leaves the channel having a plurality of holes. A deflector is immediately adjacent to each hole, and the deflector is in line to deflect the two-phase mixture towards one end of the channel. A liquid return zone is defined by the space between two channels and laterally adjacent to each other. Disengaged liquid from the two-phase mixture collects in the liquid return zones and passes through slots in the channel sides to re-enter the channel. The baffle system has an inlet weir which blocks off one end of the or each two-phase channel, so that inlet liquid is fed to the liquid return zones. An outlet weir blocks off the other end of the or each two-phase channel and the liquid return zones.
