Raschig Ring

Raschig Ring

Friedrich August raschiga invented these rings in 1880, but only patented them in 1910. Due 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 goes to the bottom passes through the same paths that the nozzle formed, and there is enough time for the gas to bind to the liquid and react.
