1481626 Contact structure for vapour/liquid contact GLITSCH INC 17 Oct 1974 [18 Oct 1973] 45069/74 Headings B1F and B1R A grid structure arranged to be positioned in a vapour-liquid contact vessel comprises a first zone including at least one layer of a plurality of spaced flange-free ribs arranged to substantially uniformly distribute liquid, a second zone including at least one layer of a plurality of spaced ribs, at least some of which ribs have flanges for promoting liquid/vapour contact, and a third zone including at least one layer of a plurality of spaced ribs, at least some of which ribs have flanges with inclined margins, the structure being formed so that when it is positioned in the vessel the first zone is above the second zone, which is above the third zone, the flanges comprise horizontal or substantially horizontal flat surfaces and the margin of the flanges in the third zone are inclined upwardly to form the sides of liquid collecting troughs. The arrangement of ribs of the first zone may be as shown in Fig. 2A, of the second zone as shown in Fig. 3A with individual ribs as shown in Figs. 6, 7A, 7C, and 13C, and the arrangement of ribs in the third zone may be as shown in Fig. 4 or Fig. 3A when inverted.
