<p>Trickling sheet for a packing device of a counterflow liquid-gas contact facility, possessing, in the vertical direction of the sheet, when the latter is in operation, an alternation of basic undulated zones (ZB) and of transitional zones (ZT) equipped with bosses (2) for the spacing and fastening of the sheets relative to one another, the basic zones (ZB) comprising two types of undulations, namely primary undulations of sinusoidal form, the crest lines of which extend vertically, as defined above, and secondary undulations of much lower amplitude and of much smaller pitch than the primary undulations, on which they are superposed, whilst at the same time intersecting them. <IMAGE></p> |
