Liquid distributor for a heat exchanger and mass transfer, distillation column with such a distributor and use of such a column for air distillation

摘要

The distributor (2) comprises a pattern of spraying points at an advantageously substantially constant surface-area pitch (6, 6') on the majority of the spraying surface, the pattern being typically uniform in a main zone of the distributor and irregular, with associated surface-area zones which are also irregular (6', 6'') in a connecting zone, the spraying points delivering predetermined flow rates defined by calibrated orifices (4, 4', 4'') which have sections chosen from a predetermined group of n sections, n not exceeding four and advantageously not exceeding two. Application especially to packed air distillation columns. IMAGE
