Raschig Super ring Raschig Super-Ring is a modern, high-efficient packing used for intensification of absorption and distillation processes. The aim of this work is to characterize the efficiency of this packing applied to rectification of ethanol-water. Its efficiency is compared to that of some random packings of the third generation as well as to structured packings.   Super Raschig Ringdetail  Super Raschig Ring  The design of the Super Raschig Ring offers an optimal solution to industry's demands for a modern heavy-duty packing. Unlike previous packing shapes, the Super Raschig Ring avoids the droplet formation which is such a frequent interference accompanying large gas loads.  The Super Raschig 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%.  Data of Metal Super Raschig Ring Size mm NO.per m3 Surface m2/m3 Free Volume % 15 180.000 315 96 20 145.000 250 97 25 46.500 180 98 30 32.000 150 98 38 13.750 120 98 50 9.500 100 98 70 4.300 80 98
