Abstract: Disclosed is a method and apparatus for alternatively feeding liquid to be distributed in a chemical process tower through a plurality of liquid distributors positioned at the same level within the tower. Very low flowrates with very uniform liquid distribution is achieved with this invention.

Abstract: A redistributor assembly for a liquid-vapor contact tower including a liquid collecting apparatus, a ladder-type liquid redistributor disposed beneath the collecting apparatus, and at least one conduit in fluid communication connecting the collecting apparatus and the ladder-type redistributor. The assembly is capable of uniformly redistributing liquid within the liquid-vapor contact tower at ultra-low flow rates by impressing a high pressure on the liquid at the point where the liquid is just about to enter the assembly's redistribution outlets. The collecting apparatus is disposed sufficiently far above the ladder-type redistributor to provide the level of liquid in the conduit that produces the desired pressure head on the liquid within the ladder-type redistributor.
