Packing element having strips with asymmetrical arch or wave shapes

Packing element, suitable for mass and/or heat exchange columns, through which at least one gas and/or at least one liquid flow flows, the packing element comprising:

• a plurality of neighbouring strips curved inwards and/or outwards,
• wherein each strip is connected to neighbouring strips at at least one end thereof,
• wherein at least one of the strips has an irregular shape, such that the at least one strip is curved perpendicular to a longitudinal axis of the packing element in an arch or wave shape and includes at least two changes of direction of its slope, whereby the arch or wave shape of the at least one strip is such that the slope changes a digit sign at least twice and the arch or wave shape of the at least one strip is asymmetrical, so that the at least one strip does not have any symmetry in itself, wherein the at least one strip has at least two vertices and has different heights in at least two of the vertices,
• wherein another strip of the plurality of neighbouring strips is a split strip that is split into two segments transverse to its longitudinal direction, and
• all strips have different shapes, so that a cross-section of the packing element is interrupted perpendicular to its longitudinal direction by numerous webs which, while they intersect each other, do not overlap in major regions.
