Product Description

Description:

Plastic Ralu Ring is an improved pall ring, it is the fourth-generation packings which have prominent characteristics compared to the other types. Its open structure ensures a regular flow through the packed bed resulting in a minimal pressure drop.
 
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.

Character of Ralu Rings
- High permeability to gas and liquid flow
- Large void fraction
- High mass transfer effeciency
- High mechanical stability
- Low tendency to maldistribution
 - Low danger of fouling

Materials:  PE (polyethylene), PP (polypropylene), RPP (reinforced polypropylene), PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride) and PVDF (polyvinylidene fluoride).

Applications
Applied in all kinds of separation, absorption and desorption device
Applied in desulfurization and decarbonization
Used in atmospheric and vacuum distillation device
Used in carbon dioxide degassing and vacuum distillation
Used in ethylbenzene, iso-octane and toluene separation

Package    Plastic bags.
Working Temperature:   60-150ºC
