16 × 16 × 0.3 mm SS304 Pall Ring Metal Random Packing in stock

1. Metal Pall Ring Random Packing Basic Info:

Pall ring packing is a kind of open-window ring packing with equal height and diameter. It is based on the RASI ring packing, a window hole with inward extending tongue leaves is opened on the ring wall. Each layer of window hole has 5 or more tongue leaves, each tongue leaf is bent inward to the ring center, and staggered from the positions of the upper and lower layers of window holes. Generally, the opening area accounts for about 30% of the total area of the ring wall. Without increasing the surface area of the packing, the gas-liquid two-phase flow in the packing layer is greatly improved, and the hydrodynamics and mass transfer performance of the packing are improved.

3. Pall ring random packing application

It is applicable to various separation, absorption and desorption devices, atmospheric and vacuum units, synthetic ammonia decarbonization and desulfurization systems, ethyl benzene separation, isooctane / methyl benzene separation, etc.

Pall ring packing has the advantages of large flux, low resistance, high separation efficiency and large operation flexibility. Under the same pressure reduction, the treatment capacity can be more than 50% larger than that of raschig ring. At the same treatment capacity, the pressure drop can be reduced by half and the mass transfer efficiency can be increased by about 20%. Compared with raschig ring, this kind of packing has the characteristics of large production capacity, small resistance and large operating flexibility. In general, when the pressure drop is the same, it can treat 50% - 100% more than raschig ring, and when the capacity is the same, its pressure drop can be 50% - 70% lower than raschig ring. Pall ring can also help reduce the tower height. Using Pall ring can save 20% - 40% of packing volume than raschig ring.

Hualai pall rings are available in several sizes as indicated on our design sheets to suit most commercial applications. They range in size from 10mm to 76mm or equivalent. It is an essentially a design consideration in specifying a packing size based on capacity and efficiency requirements. The nominal packing size specified should however not be greater than 1/10th of the column diameter.
