Claim:
1. A contactor for a column intended for heat and/or material exchange between two fluids, comprising at least one packing layer comprising an arrangement of at least a first structured packing and a second structured packing, the second structured packing developing a specific geometric surface area, expressed as a geometric surface area of the packing per volume unit, greater than the specific geometric surface area of the first structured packing, the first structured packing has a principal direction through and along hollows between corrugations of plates of the first structured packing corresponding to an orthogonal direction to a vertical axis, the second structured packing has a principal direction passing through and along hollows between corrugations of plates of the second structured packing corresponding to an orthogonal direction to a vertical axis, and the principal direction of the first structure packing is parallel to the principal direction of the second structured packing.
