Plastic Pall Ring
Capacity versus Pressure Drop of AceChemPack Plastic Pall ring, Most suited in low pressure drop, high capacity applications, A range of sizes of AceChemPack 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. AceChemPack Plastic Pall ring has an advance on the Plastic 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.
Versatility of AceChemPack 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.
Mechanical Strength of AceChemPack Plastic Pall ring, Its internal cross-structure of diametrical spars make it mechanically robust and suitable for use in deep packed beds.
Application:
AceChemPack Plastic Pall rings are 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: PP,PE,PVC,CPVC,PVDF,PTFE,PFA etc.
