Pall ring is a open-hole ring packing,which high and diameter is the same and with 5 ligules toward inside at every floor. Usually the open surface is 30% of the whole wall surface, this character helps the liguid & gas pass in packing tower pass freely from the windows of the rings.
Metal Pall Ring has features such as thin wall, heat resistant, high free volume, high capacity, low resistance, high separation efficiencyand so on. It is especially suitable for rectification towers under vacuum to treat thermo sensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.
1. Increased loading and plant capacity;
2. Reduced pressure drop;
3. Improved resistance to fouling;
4. High mass transfer efficiency;
5. Easily wettable;
6. High temperature applications, mechanically robust, lesser probability of breakage, so it is very suitable for deeper beds.
