Pall rings are used extensively in both new and retrofit installations. Unlike Raschig rings, the walls of
our pall rings are open. The high percentage of free space maintains superior, uniform liquid
distribution. The ring's open space also provides gas and liquid full access to the ring's interior. The
interior of each ring has diametrical ribs, which provide structural strength as well as additional surface
area for gas-liquid contact.
Features: Pall Ring has a low pressure drop, large void space and high efficiency.
Applications: It is applicable to all kinds of separation, absorption equipment, atmospheric and vacuum
distillation unit, synthetic ammonia decarbonization and desulfurization systems, ethylbenzene
separation, isooctane, toluene separation, etc.
Plastic Pall rings – appointed for infilling of active volumes and apparatus to increase the intensity of heat and mass transfer process in equipment of chemical, petrochemical, oil refining industries and other fields of manufactory, water supply and canalization system, ammonia and mineral fertilizers production.
Plastic Pall rings are irregular packing. Acid resistant ceramic packing are appointed for infilling of the column packing and other heat and transfer apparatus, that works under the temperature to 120 Celsius degrees for acidic media.
In comparison with Raschig rings, Pall rings have better absorbing capacity and reduced pressure drop, have better effectiveness of separation and the degree of wetting due to the perforated structure. Open structure of the packing ease the uniform loading pf packing and reduce and this reduces the losses.
