Product Description

Plastic Pall Ring brief introduction:

Plastic pall ring is versatile, and plastic pall ring is an advance on the raschig ring. The plastic pall ring has similar cylindrical dimensions as plastic raschig ring, but it 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. LianChuang Plastic pall ring’s this structure significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.

LianChuang can provide pall ring in a variety of plastic, such as PP, Polypropylene, PVC, PVDF, HDPE and Glass Filled Polypropylene etc.

Features of plastic pall ring:

Plastic pall rings are suited in low pressure drop, high capacity applications, and raschig rings has range of sizes allows the tower to operate at an optimum efficiency and throughput. With the character high degree of randomness, consistent ratio of free and blocked passages, independent of orientation, plastic pall ring also has large surface area, the volume ratio augments the rate of liquid film surface renewal to improve mass transfer. Plastic raschig rings’ internal cross-structure of diametrical spars make it mechanically robust and suitable for use in deep packed beds. Plastic pall ring could also promote highly efficient two-phase contact and distribution with a relatively high liquid hold-up promotes high absorption efficiencies, especially in cases where the reaction rates are slow, uninterrupted and consistent passages for gas and liquid flow.

Application of plastic pall ring:

Plastic pall ring is widely used in absorption, scrubbing, and stripping services, versatile alternative to metal pall ring, all kind of separation, constant decompress tower plants, compounding ammonia plant, decarbonization plant, separation of ethylbenzene, seperation of isooctane or methylbenzene.
