Plastic Pall Ring, is designed based on the Plastic Raschig Ring.
It has similar cylindrical dimensions but has two rows of punched out holes.
The structure improve distribution of gas-liquid and its efficiency can be improved above 50%, and only has half of pressure drop compared with Raschig Ring.
plastic Pall Ring, is made form heat resistant and chemical corrosion resistant plastics.
It has features such as 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℃ to 150℃.
Available materials
Polypropylene (PP).Polyethylene (PE).Polyvinyl chloride (PVC).Chlorinate polyvinyl chloride (CPVC).Polyvinylidene Fluoride (PVDF).Reinforced Polypropylene (RPP)
Applied in various mass transfer towers for stripping, scrubbing and absorption.Used in the industries of chemical, gas, petroleum, chlor-alkali and environmental protection.Used in carbon dioxide degassing towers, ozone exposure reaction towers, vacuum distillation towers and other reaction towers.
