AbstractLiquid distributor in packed column wherein close, long-term uniform liquid distribution pattern is desired, particularly at ultra-slow distributing flow-rates. Distributor comprised of: (1) array of spaced, enclosed, horizontal distributor tubes capable of maintaining liquid to be distributed under pressure; (2) horizontal tube lines connecting these tubes; (3) vertical pipelets of predetermined inside diameter and length inserted into bottoms of distributor tubes and extending above bottom of tubes but not to top of tubes to avoid being stopped-up by debris in the liquid; and (4) a pressurized feed means. For feeds containing both liquid and vapor phase, a parting reservoir is provided above the distributor so that the vapor phase of the feed entering the reservoir can escape the liquid phase leaving the liquid phase to flow down a conduit into the distributor tubes, said conduit being of predetermined height above the tubes so as to provide liquid under constant pressure to the distributor tubes.
