Plastic Ralu ring is improved based on the plastic Pall ring. The main improvement is the adding of turn-ups in two ends and the thickness of the ring wall. As its special structure, it has lower bed height and lower pressure drop than plastic Pall ring. Plastic Ralu ring also has higher capacity and better efficiency
As plastic Ralu ring's high flooding point, uniform gas-liquid contact, it can be used in devices of reducing pressure, separation and absorption process, isolation of ethylbenzene, toluene, trimethylpentane, etc.
We offer a wide range of plastic Ralu ring that is made of heat resistant and chemical corrosion resistant plastics.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
Large flux and small resistance
High mass transfer efficiency
Low mass-transfer unit height
High separation efficiency
As its high performance, plastic Ralu rings are widely used in all kinds of separation, absorption and desorption device, vacuum distillation device, decarburization and desulfurization system, ethylbenzene, iso-octane and toluene separation, etc.
