Raschig Ring

Raschig Ring

Raschig Ring

Friedrich August Raschig invented these rings in 1880, but only patented them in 1910. Thanks to the simple cylindrical shape of the tube with an aspect ratio of 1: 1, the liquid moves through thousands of channels formed by rings, inside and outside the surface, gradually moving to the bottom. The gas that enters the bottom passes through the same paths that the packing formed, and there is enough time for the gas to bind to the liquid and react.
