SS 304 Knitted Wire Mesh Metal Tower Strucutured Packing For Distillation 500Y
Metal Tower Packing Description
Metal structured packing is formed from thin corrugated metallic plates or wire gauze, which at uniform geometry arranged and neatly piled in the tower. Metal structured packing is widely used in absorption and distillation columns and chemical reactors. It has large surface area, low pressure drop, uniform fluids, heat and mass transfer efficiency and other advantages.
Metal Wire Gauze Packing is characteristic of good low-load properties, large number of plates per meter in theory, and the number of plates will decrease with gas load increasing. The packing can meet the demand for accurate, large-scale, high vacuum distilling apparatus, and provide convenient conditions for distilling separation of some system difficult for separating, heat-variable system and high-purity products.
Metal Tower packings is assembled by rolling small profile and bellows in metallic sheet surface. With the advantages of low resistance, uniform distribution of gas-liquid, high efficiency, big flux, not obvious enlarging effect, it is applied to vacuum or pressure operation.
Metal Structured Packing Specification
| Type | Surface area | Void fraction | Bulk density | Wave height | Nt | ΔP | Max.F-factor |
| m2/m3 | % | kg/m3 | mm | m-1 | Pa/m | m/s.(kg/m3)0.5 | |
| 125 | 125 | 98 | 85-100 | 25.4 | 1-2 | 150 | 3 |
| 250 | 250 | 97 | 170-200 | 12.5 | 2-3 | 200 | 2.6 |
| 350 | 350 | 94 | 240-280 | 9 | 2.0-2.5 | 300 | 2 |

Metal Structured Packing Application
Metal Structured Packing with high flux, low resistance, high efficiency, the advantages of anti-blocking ability. In distillation, absorption, and extraction unit operation widely used, According to filler type, the minimum diameter of 80- 200mm, maximum diameter reached 13m, density of the liquid spray from 0.2-220m /m .hr, the pressure range from vacuum to high pressure. Is used in chemical, fertilizer, oil refining, petrochemical, natural gas and other industrial versatile and efficient structured packing. Theoretical plate number of the packing high flux, low pressure drop, low load, performance, operating flexibility, amplifying effect is not obvious.
Used in fine chemicals, spices, isomer separation, difficult to isolate system, heat-sensitive substances and products of high purity distillation, separation has significant results.
Metal Structured Packing Features
(1) High capacity. New tower design may reduce diameter, while renovate old towers
may increase capacity significantly.
(2) High separation efficiency. Since it has much larger specific surface area compared
to random packing.
(3) Low pressure drop, which leads to reduce energy consumption largely.
(4) Large flexibility, and scale effect is not obvious.
(5) Suitable for all tower diameters.
(6) Strong resistance to corrosion of acid and alkali, especially to H2S, naphthenic
acid and Cl- .
