The invention is a method of formation and a structured packing for a fluid exchange column, which defines an exchange surface for at least one descending liquid phase to be placed in intimate contact with at least one ascending gaseous phase. The packing comprises a stack of plates having undulations, each plate being contained in a space included between two parallel planes L1 and L2 separated by a value of between 5 and 50 mm. The undulations are distributed on both sides of a center plane P separating the space into two equal parts and form a series of channels which extend along a direction D. The channels comprise wings contained in the space included between the two parallel planes. Each wing is composed of a strip B punched out in one of the channels according to at least two grooves C1 and C2. The width of the strip between the two grooves is between 1 and 15 mm. The strip B is stamped/embossed to create an orifice forming a discontinuity in the surface of the channel at the level of the two grooves C1 and C2.
A structured packing of a fluid exchange column defining an exchange surface for at least one liquid phase to be placed in intimate contact with at least one ascending gaseous phase, comprising a stack of plates including triangular undulations, each plate being contained between two parallel planes at a distance of between 5 and 50 mm, the triangular undulations forming a series of continuous and triangular channels including wings projecting from the continuous and triangular undulations contained between the two parallel planes, each of the wings, being composed of a strip fabricated in one of the channels, a width of each strip being between 2 and 20 mm, each strip being fixed to the plate by two ends thereof and each strip being triangular in shape to provide a triangular form symmetrical relative to an initial form prior to fabrication thereof with respect to a central plane of the two parallel planes to create an orifice forming a discontinuity on a surface of each plate.
