Plastic Pall Ring

Plastic Pall Ring has 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.

Capacity versus Pressure Drop of Plastic Pall ring, most suited in low pressure drop, high capacity applications. A range of sizes of Plastic Pall rings allows the tower to operate at an optimum efficiency and throughput, consistent ratio of free and blocked passages, independent of orientation. Large surface area : volume ratio augments the rate of liquid film surface renewal to improve mass transfer. Hold-up and Two-phase Contact, Promotes highly efficient two-phase contact and distribution; 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.

Versatility of Plastic Pall ring, Open, cross-linked design provides a highly efficient used of the ring’s surface area, robust to variations in liquid and vapour distribution.

Material:Polypropylene(PP), Reinforced Polypropylene(RPP), Reinforced Nylon 6, Reinforced Nylon 66…

Features: The Pall Ring has the characteristic of low pressure drop, big flux, high efficiency. Compared with the Pall Ring of the same size, HYPAK packings has lower pressure drop and higher transfer efficiency. Furthermore, it has good liquid distribution in the packing layer. 

Application: It is used in various seperation, adsorption, deadsorption equipment, normal pressure drop equipment, decarbonization of synthetic ammonia, desulphurization, seperation of ethylbenzene, isooctane or methane.

Specification:
