Plastic Raschig ring is a pieces of tube, approximately equal in length and diameter, which is named after the inventor, German chemist Friedrich Raschig. And it is the first-generation tower packing with a unique hollow cylindrical shape.
Due to its simple structure and light weight, it is easy to manufacture and operate. Plastic Raschig ring is characterized by large flux, lightweight and excellent corrosion resistance. It is widely used in various stripping, degassing, absorption and distillation processes, extensively used in the petroleum industry, chemical industry, alkali-chloride industry and gas industry.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
Large flux and low pressure drop
Strong corrosion resistance
Easy to operate and economical
High separation efficiency
Characterized by large flux, lightweight and excellent corrosion resistance, plastic Raschig ring can be used in ethylene extraction columns, mass-transfer columns separation devices, carbon dioxide and absorbers and flash tower, liquid extractors, carbon monoxide converters, dimethyl terephthalate hydrogen sulphide running column, NH3 extraction devices, petrochemical and medical equipment, etc.
