Plastic Pall Ring with High Mass Transfer Velocity

A 360° overview of plastic pall ring on the blue background.
PPR-01: 360° shows of plastic pall ring for comprehensive understanding.

Plastic pall ring is also called plastic pall ring packing. It is a type of random packing, which modifies directly at the shortcomings of raschig ring. This type pall ring makes some structural improvements on the basis of raschig ring. It adds many small rectangular windows on its wall. The blades of these small rectangular windows join together in the center of the pall ring. The openings on plastic pall ring's lateral wall fully utilize its internal surface area and greatly increase the gas-liquid agitation. Therefore, plastic pall ring has better gas-liquid distribution performance than plastic raschig ring.

Plastic pall ring is characterized by high gas velocity, small resistance and large production capacity. It performs well in stripping and scrubbing. This kind pall ring packing has good chemical resistance, it is suitable for various industries, such as chlor-alkali industry, gas industry and chemical industry. It is widely used in carbon dioxide degassing towers, ozone exposure reaction towers, vacuum distillation towers and other reaction towers.

There is a white plastic pall ring. It has many rectangular small openings.
PPR-02: The rectangular openings of plastic pall ring largely increase its internal surface area and mass transfer velocity.
There are two white plastic pall rings.
PPR-03: Plastic pall rings are available in various materials, such as PE, PP, RPP and CPVC.

Specifications:

  • Material: PE (polyethylene), PP (polypropylene), RPP (reinforced polypropylene), PVC (polyvinyl chloride), CPVC (chlorinated polyvinyl chloride) and PVDF (polyvinylidene fluoride).
  • Lifespan: more than 3 years.
  • Package: plastic bags, cartons.
