Overview
Pall Ring, an enhancement on Raschig Ring, forms one of the most common random packing and is generally used in gas and liquid transfers. Its improved design saves up packing volume by increasing surface area, boosting the performance of packing.
Pall Ring’s open-wall design and cross-link structure not only allows lower pressure drop with greater capacity, but also enhances the distribution of gas and liquid. This innovation renders high mass transfer efficiency and improves the rate of separation.
