Pall Ring
Pall Ring, an enhancement on Raschig Ring, forms one of the most common random packing and is generally used in gas and liquids transfers. Its improved design saves up packing volume by increasing surface area, boosting the performance of packing.
Common Applications
Various kinds of separation, absorption, distillation, stripping, scrubbing, environmental applications, etc.
Features
· Lower pressure drop
· High mass transfer efficiency
· High flux and low resistance
· High liquid holdup
· High separation efficiency
