The design of the Raschig Super-Ring® offers an optimal solution to industry's demands for a modern heavy-duty packing. Unlike previous packing shapes, the Raschig Super-Ring® avoids the droplet formation which is such a frequent interference accompanying large gas loads. The alternating wave structure has produced not only a shape which is open on all sides, but at the same time a large number of contact points for homogeneous distribution of liquid and gas.  The Raschig Super-Ring® has a more than 30% greater load capacity, an almost 70% lower pressure drop and a mass transfer efficiency exceeding that of conventional metal packings by over 10%. The development of the new "Raschig Super-Ring®" packing element sets new standards in the field of separation technology, as the designer so the Raschig Super-Ring® have succeeded in finding an optimum link to those demands which a modern, high-performance packing element must fulfill under industrial conditions. Also available is the Plastic "Raschig Super-Ring®" which sets new performance standards in the use of mass transfer columns.  The Raschig Super-Ring® optimized fluid-dynamic design produces an effective mass transfer between the phases flowing in the column. It achieves large interfaces and an even distribution of the liquids over the column cross-section. High loading capacities permit large column throughputs, and low pressure drops yield low operating costs.

The revolutionary idea behind the design of the Raschig Super-Ring® has now also led to exceptionally good mass transfer efficiencies, pressure drops and loading capacities in the FRI test facility. The structure of the Raschig Super-Ring® is the first to pursue the objective of producing turbulent film-type flows and to prevent formation of drops. The large number of alternating wave swings also achieves large turbulence in the gas and liquid flow while at the same time it has an extremely open geometry. Owing to the fluidically optimized shape of the Raschig Super-Ring®, the randomly dumped packed bed automatically obtains a structure otherwise found only in the case of structured packings. Table 1 below gives a brief summary of the previous applications of the Raschig Super-Ring®. The exceptionally good chemical engineering data were confirmed both in rectification and in absorption and desorption columns. Numerous mass transfer processes are operated with extreme dumping heights (up to to 11m) without liquid redistributors. These dumping heights can be achieved since the liquid and gas phases are distributed extremely evenly over the column cross section due to the optimal packing geometry, thus preventing mass transfer losses along the mass transfer column.
