Raschig rings are usually made of ceramic or metals, and they provide a large surface area within the column, allowing for interaction between liquid and gas vapors. [7] Due to its large flux and low resistance, metal raschig ring performs well in gas-liquid distribution. Given the success of the Raschig ring, there have been other forms developed to either improve upon it, or to avoid patents for particular designs. Ft. =.0283 cu.

Raschig rings belong to an earlier, less sophisticated generation of packing material. Raschig rings are tubular pieces commonly used as random packing materials in chemical processing and mass transfer operations, such as fractional distillation. This packing allowed for greatly improved process efficiencies in his plant. They are also used for devices where gas and liquid are put in contact for purposes of gas absorption, stripping or chemical reaction, and as a support for biofilms in biological reactors. 0.7 Test; Report of Raschig Super Rings ® No. Contact Info ; Products .
