Plastic Flat Ring tower packing

Short Description:

Plastic Flat ring has a small ratio of height to diameter, about 1:3. Due to its structure’s change, effectively reducing the filler layer axial back mixing so as to improve the liquid-liquid mass transfer efficiency between two phases. Moreover, it is suitable for such packing liquid-liquid mass transfer of the extraction process. The Flat ring packing is similar to ring of the Cascade Mini Ring on the structure, but there are no top turn ups, guarantee packing unify orientation when piling up, increase pile density, make packing layer liquid distribute further more even improved inside separate.

Feature		High void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer.
Advantage		1. Their special structure make it has big flux, low pressure drop, good anti-impaction capability. 2. Strong resistance to chemical corrosion, large void space, energy saving, low operation cost and easy to be load and unload.
Application		These various plastic tower packing are widely used in petroleum and chemical, alkali chloride, gas and environmental protection industries with max. temperature of 280°.

Physical & Chemical Properties of Plastic Flat Ring

Plastic tower packing can be made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), polyvinyiidene fluoride (PVDF) and Polytetrafluoroethylene (PTFE). The temperature in media ranges from 60 Degree C to 280 Degree C.
