Abstract: The invention relates to a cross-flow base for a material exchange column (27) in which a gas a guided in counterflow to a fluid, wherein the cross-flow base (1) has through openings (3) for the gas and at least two drain shafts (5), wherein the drain shafts (5) project over the upper side of the cross-flow base (1) and a collection cup (13) is arranged underneath each drain shaft (5). The drain shaft (5) projects into the collection cup (13), the minimum horizontal cross-sectional area of the collection cup (13) is 1.2 to 4 times larger than the horizontal cross-sectional area of the drain shaft (5) at the outlet, and the collection cup (13) has a circumferential wall (15) with an overflow device (19). The invention also relates to a material exchange column containing the cross-flow base, and to a use of the material exchange column.
