Graphite Raschig ring is a kind of graphite material ring, with the same circle and diameter, chemical packing which is resistant to hydrogen, acid, strong acid and alkali. The temperature can be as high as 200 ºC, and the temperature can reach 48% of the corrosion resistance with sulfuric acid, potassium hydroxide, organic acid salts, most solvents and alkaline substances such as sodium hydroxide, etc.

The graphite Raschig ring has the characteristics of low pressure drop, large flux, uniform liquid distribution, high mass transfer efficiency, and can absorb various exhaust gases or be used for gas washing and separation. It replaces a large number of ferrous metals and a variety of non-ferrous metals, and is a non-metallic material with excellent corrosion resistance.
Graphite Raschig ring packing is mainly used in practical applications such as gas absorption, acid gas desorption, scrubbing tower, regeneration tower, fertilizer production, etc. It can also be used as a packing in propane stripper and acid gas absorber. It is used in the furnaces and towers of petrochemical equipment such as alkylation and reforming, and in the purification, absorption, condensation, distillation, evaporation, filtration and washing of highly corrosive materials.
