Specific Application:
Widely used in petroleum and chemical industries, alkali chloride industries, gas industries and environmental protection industries with max.
Summary:
1) Material: PE, PP, PVC, PVDF, CPVC...etc 2) 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
Plastic pall ring is made from heat resistant and chemical corrosion resistant plastics, including polyethylene (PE), polypropylene (PP), reinforced polypropylene (RPP), polyvinyl chloride (PVC), chloridized polyvinyl chloride (CPVC) and polyvinylidene fluoride (PVDF). 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 60to 150. For these reasons it is widely used in the packing towers in petroleum industry, chemical industry, alkali-Chloride industry, coal gas industry and environmental protection, etc... The structure of Pall Ring improves distribution of gas-liquid. Its efficiency can be improved 50%. Compared with Raschig Ring, it has half of presure drop.
