Packing module, method for making same, and fluid treating apparatus comprising a corresponding packing

摘要

The invention concerns a packing module (2) comprising an assembly of deflectors (7, 9, 11) which define a set of horizontal layers of fixed mixing ventilators (3, 4, 5). In at least one axial end zone (6) of the module, the deflectors constitute transition deflectors (9, 11) defining at least one layer of fixed transition ventilators (4, 5) whereof the mixing effect is reduced relative to that of the layers (3) located in the current part of the module. The invention is useful for air distillation columns.
