Over the years many shapes have been proposed for tower packing elements, but by yourself a few are widely used. Probably the oldest random dumped tower packing rework in substantial public notice use is the raschig sports ground. This packing is a easy cylinder subsequent to a length equal to its outdoor diameter. It is manufactured from ceramics, metals, plastics, and carbon. Two modifications of this influence are the Lessing sports ground and the cross-partition arena. Both of these shapes use internal partitions. These packings have been installed in both a dumped and a stacked ventilate.
A adjunct modification of the basic cylindrical impinge on involves installation of a helix inside the cylinder. The interior of this ground may contain a single, a double, or a triple helix. This spiral arena packing normally is made from ceramic and only should be installed by stacking.
The first of the futuristic dumped packing was the berl saddle, developed in the late 1930s. This panic signal has a significantly increased surface place per unit of packed volume compared to the raschig ground. Another augmented touch was the intalox saddle developed in the yet to be 1950s. This design has two every second radii of curvature that pay for a greater degree of randomness in the packed bed.
In the forward 1950s a significant go into detail was made in the raschig arena impinge on by BASF. Their sustain, called the Pall arena, consists of a cylinder of equal length and diameter as soon as ten fingers punched from the cylinder wall that extend into the packing element interior. Although the Pall arena has the
connected geometric surface place as the Raschig auditorium, the interior surfaces of the Pall auditorium are much more accessible to gas and liquid flows due to the
openings through the wall. Subsequent Pall auditorium modifications, such as Hy-Pak packing that have supplement increased the percentage of internal surface area the packing element makes comprehensible for gas and liquid right of entry.
A subsidiary modification of the Pall showground was developed by Mass Transfer Limited. Their Cascade Mini-Ring with is a cylinder as soon as fingers punched from the wall projecting into the interior of the arena; however, the extremity of the cylinder is on your own one-third the outside diameter. This concern is said to orient itself preferentially later than dumped into a packed bed.

A newer packing element combines advantages of the be wishy-washy of the intalox saddle as soon as that of a objector arena packing. This intalox metal tower packing, or IMTP packing (trademarks Norton Chemical Process Products), was developed by Norton Company in the tardy 1970s and is manufactured from metals single-handedly.
