<p>The invention describes a structured packing for a fluid exchange column, said structure defining an exchange surface for at least one descending liquid phase intended to be brought into intimate contact with at least one ascending gaseous phase. The packing is made up of a stack of corrugated plates, each plate being fitted into a space lying between two parallel planes L1 and L2 separated by a distance of between 5 and 50 mm, the corrugations being distributed on either side of a mid-plane P separating said space into two equal fractions, said corrugations forming a succession of channels that run along a direction D, the channels having fins fitted into the space lying between the two parallel planes, each of said fins being made up of a strip B cut from one of said channels into at least two notches C1 and C2, the width of the strip between the two notches being between 1 and 15 mm, the strip having two ends E1 and E2 fastened to the channel, and the strip B being dished so as to create an orifice forming a surface discontinuity of the channel at the two notches C1 and C2. The invention also describes a method of manufacturing a structured packing.</p> |
