Plastic Ralu Ring is an improved pall ring, their open structure ensures a regular flow through the packed bed resulting in a minimal pressure drop.
Plastic ralu rings are made of heat resistant and chemical corrosion resistant plastics including PP, PE, RPP, PVC, CPVC and PVDF.
Plastic Ralu Rings are featured with high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60°C to 280°C.
Plastic ralu ring is widely apply in all kinds of separation, absorption and desorption device, atmospheric and vacuum distillation device, decarburization and desulfurization system, ethylbenzene, iso-octane and toluene separation.
