металл Pall кольца

Metal pall rings areone of the most common and well known random tower packings Metalpall rings arean industry standard design media developed from the raschig rings andare used widely in variety of applications By improving the metal pall rings geometry enables high gas and liquid transfer rates, greater capacity and lower pressure drop than standard cylindrical rings. The interior and exterior contacting surfaces of the metal pall rings provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting Technical data of metal pall rings: Specifications (mm)D*H*δ (mm)Bulk number (n/m³)Specific surface area (m²/m³)Bulk density (m²/m³)Void volume (m³/m³)Dry packing factor (m-1)Dg1616*16*0.51430002392160.928299Dg2525*25*0.555900219414.20.934269Dg3838*38*0.7130001293120.945153Dg5050*50*0.86500112.33120.949131Dg7676*76*11870682160.962 Material of metal pall rings: Metal pall rings are available in a wide range of materials, such as stainless steel, carbon steel, 304, 304L, 410, 316, 316L, aluminum, bronze, and other alloy Advantage of metal pall rings: 1.Lower pressure drop 2.Good liquid / gas distribution and higher mass transfer efficiency 3.Versatility, easily wettable, high resistance to fouling, high temperature 4.High Mechanical Strength, suitable for deeper beds 5.High temperature resistance Application of metal pall rings: Metal pall rings are widely used in all kinds of separation, absorb plants, constant decompress plants, compounding ammonia plant, decarbonization, desulfuration, separation of ethylbenzene, separation of isooctane/ methylbenzene, Absorption, Aeration, Degassing, Desorption, Distillation, Stripping, Heat Recovery, Extraction, Various separation and absorption applications at atmospheric pressure and under vacuum, where a low pressure drop is critical, H2S, NH3 & SO2 Absorption & Stripping, Steam Stripping, Quench towers, Direct contact cooling
