ABSTRACT:
A liquid distributor for a packed liquid-vapor contact column includes a header tank; a liquid distribution plate having vapor riser passages and a multiplicity of discrete reservoir cells each having an aperture for flow of liquid therefrom into the column; and conduits for feeding liquid from the header tank into each cell. The liquid distribution plate preferably has a uniform criss-cross structure with alternating vapor riser passages and reservoir cells of identical shape and size. The conduits may have two or more sections each feeding a discrete group of reservoir cells from a location of the header tank at an elevation spaced from that of the other section(s). The distributor compensates for column sway or tilt when mounted on, for example, a ship.
