Plastic random packing PVDF polypropylene packing pall rings
Packing Pall ring is made from heat resistant and chemical corrosion resistant plastic , for instance. polypropylene (PP). An advance on the Raschig Ring, the Pall Ring has similar cylindrical dimensions but has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.
Pall Ring Features:
1. Higher capacity and lower pressure drop than ceramic packing.
2. Multiple sizes provide ability to optimize capacity and efficiency based on application requirements.
3. Relatively high liquid hold-up allows good absorption efficiency with slow chemical reaction. 4. Lower sensitivity to liquid and vapor distribution quality allows use with conventional liquid distributors.
5. Ring and spoke construction provides high mechanical strength, which allows use in deep beds.
