The difference between Pall ring packing and Raschig ring packing

- Sep 13, 2019-

The Pall ring packing has the advantages of large flux, low resistance, high separation efficiency and large operational flexibility. Under the same pressure reduction, the treatment volume can be more than 50% larger than the Lacy ring. At the same throughput, the pressure drop can be reduced by half and the mass transfer efficiency can be increased by about 20%. Compared with the Raschig ring, this kind of packing has large production capacity and strong resistance...

The structured packing is a packing that is arranged in a uniform geometric pattern in the tower and neatly stacked. Due to its large specific surface area, small pressure drop, uniform fluid distribution, high mass transfer heat transfer efficiency, the most widely used structured packing is vertical corrugated packing. The vertical corrugated packing is divided into a corrugated type and a mesh corrugated type. In the specification type indication of corrugated packing, the figures generally represent the specific surface area values. The letters x and y respectively represent the inclination angle of the corrugation of 30 ° C, 45 ° C, for example, 400 x means that the corrugated packing has a specific surface area of 400 m 2 / m 3 , corrugation The angle of inclination is 30 °C. The pressure drop of the x-type packing is small; the mass transfer performance of the y-type packing is better.
