Structure tower packings

Structured Packing
Sulzer's Katapak Chemical Reactor filler, based on double-layer mesh made of packing, the mesh of the sandwich that has the catalyst [5]. Sulzer's Optiflow structured packing, has a unique structure, folding and punching from the sheet metal piece set


Loaded from, it changes the liquid crossing the plate filler Mellapak steady flow on the surface of the traditional model of long distance, through the twists and turns and changing the direction of the plate, to promote the dispersion of liquid - polymer - and then dispersed cycle, to ensure and good contact with gas, and to the mass transfer surface constantly updated. It combines structured packing and random packing of the advantages of both high efficiency, but also has great flux. Reported, compared with the conventional plate and fill in the same separation efficiency under the conditions of processing capacity can be increased by 20% to 25%, while in the case of the same capacity, mass transfer efficiency can be increased by 50%. Raschig's Supekpak300 Plate structured packing surface area of ​​300m2/m3. According to the manufacturer's data, and so far in the surface area comparable to the filler can be compared to it's load capacity by 26%, 33% reduction in pressure loss. Mitsubishi (strain) of Mc-pak structured packing, wire and sheet into 2 categories, screen 500 mesh, surface area 1000m2/m3. Plate class has 250S, 350S, 500S, and 500SL 4 species, surface area, respectively 250m2/m3, 350m2/m3, 500m2/m3, which 500SL for high and low pressure drop liquid load type. The general characteristics of the pressure loss, operating range, HETP small, easy to operate. Schott's Durapack glass fiber structured packing, the company's proprietary products, products for the high corrosion resistance, high-throughput, low pressure drop and good separation performance. Surface area 280m2/m3 and 400m2/m3. Porosity were 80% and 72%, textured surface is divided into rough surface and smooth surface, into DN100 ~ DN1000mm the tower. In addition, the Swiss company will also Rombopak soil Kühni series expanded to 12M type. Its surface area is 450m2/m3. Manufacturers in a tower diameter of DN50mm experiments with chlorobenzene / ethylbenzene test system under the pressure measured in 6600Pa: When the F factor 0.5Pa, the 10 theoretical plate; when the F factor is 2Pa, the 7 theoretical plate. Montz provide their tantalum Montz-PakA300 type filler, its thickness is 0.05mm. Nutter produced BSH structured material is between the town network, plate filler filler between the new and efficient, its unique inflatable fabric structure made up of metal wire mesh and sheet metal structured packing gap. BSH fabric structure of the capillary action, filling in any operating conditions that have the highest mass transfer efficiency. Filler filler opening to ensure the effective updating and filling the surface of the liquid on both sides of the exchange, to achieve the best gas-liquid contact and separation, the surface area of ​​up to 500m2/m3, to meet the needs of any separation process. It is typically used in the refinery's crude distillation tower, reactive distillation, air separation and pharmaceutical chemistry tower. BSH filler equipped with Nutter's proprietary liquid distributor, and all internals, high theoretical plate number, HETP low pressure drop.
