ABSTRACT:
A tower packing cartridge is formed of strips of fabric-like material placed in face-to-face contact such that the planes of the strips are parallel to the general flow direction through the cartridge. The fabric-like material is formed of generally straight, relatively stiff strands of mono-filament material, arranged in a repeating pattern which is preferably generally triangular in cross section in both directions. The construction provides a substantially non-nestable structure when strips are placed in face-to-face contact, such that the cartridge has an extremely high void fraction. The fabric-like material, in itself known, when assembled in this manner, achieves unique and surprising results in relation to exceptional uniformity of flow distribution across the entire face of the cartridge while at the same time maintaining extremely high void fraction to keep energy losses at a minimum during operation.
