Plastic pall ring:
PE pall ring, PP pall ring, RPP pall ring, PVC pall ring, CPVC pall ring, PVDF pall ring, PTFE pall ring, HDPE pall ring.
Plastic Pall Ring has an advance on the Raschig Ring, Plastic 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.
Advantages of Plastic Pall Ring:
1. High void ratio.
2. Low pressure drop.
3. Small specific gravity.
4. Resist chemical corrosion.
5. High mass transfer efficiency.
6. Resist nesting and wall-flow effect.
7. Gas-liquid with uniform distribution.
Applications of Plastic Pall Ring:
Plastic Pall ring is widely used in Absorption, scrubbing, and stripping services, Versatile alternative to metal Pall rings, all kind of separation, constant decompress tower plants, compounding ammonia plant, decarbonization plant, separation of ethylbenzene, seperation of isooctane/ methylbenzene.
Material: PE, PP, RPP, PVC, CPVC, PVDF.
Size: 5/8" (16mm); 1" (25mm); 1.1/2" (38mm); 2" (50mm); 3" (76mm).
