A distillation column liquid distributor has a secondary distributor (4) which has a gas headspace communicating with the column interior and which has compartments with fine liquid distribution holes (12). A liquid distributor for a distillation column comprises: (a) a primary distributor (3) which is supplied with liquid at a pressure above that within the column (2) and which has openings (8) for liquid discharge into the column; and (b) a secondary distributor (4) which occupies the entire cross-section of the column, having a gas headspace communicating with the column interior and which is subdivided by partitions (13, 17) into compartments (16) for individually receiving liquid from one or more associated primary distributor openings (8), the secondary distributor (4) having a base with a number of fine liquid distribution holes (12) which is much greater than the number of primary distributor openings (8). An Independent claim is also included for a distillation column equipped with the above distributor. Preferred Components: The compartments (16) are each associated with a single primary distributor opening (8) and have the same area and number of holes. The primary distributor (3) comprises a grid of parallel perforated tubes (7), each located directly above a rectilinear spout of the secondary distributor (4). The liquid supply system for the primary distributor (3) comprises a phase separator and a pressurized supply line, which is connected downstream to the lower part of the separator, and passes through an undercooler.
