Pall Ring for Acid Resistance --Ceramic Tower Packing
The pall ring attempts to increase the useful aspects of packing, by giving an increased number of edges to disrupt flow, whilst also reducing the volume taken up by the ring packing medium itself. Rather than using a solid-walled tube, the pall ring resembles an open basket structure of thin bars. These form both a tube and also a radial structure of cross bars.
