Disadvantages: due to the high aspect ratio, the packing is easy to form line contact during packing, so there is often serious channeling and wall-flow phenomenon when the liquid flows in the packing layer. And Raschig ring packing surface wetting rate is low, so the mass transfer rate is not high.

(2) Pall ring packing

The pall ring developed on the basis of the Raschig ring is one or two oblong holes in the side wall, and the base metal of the hole does not leave the side wall but forms the inwardly curved blade. Pall ring and Raschig ring with the same size although the same specific surface area and porosity, but the Pall ring in the small holes on the side wall for gas and liquid circulation, so that the inner wall of the ring make full use of.

Compared with Raschig ring, Pall Ring not only has greater capacity and lower pressure drop, but also has higher separation efficiency and greatly reduces channeling phenomenon.

(3)  Saddle Ring

 Saddle ring includes ceramic saddle,metal and plastic saddle ring. Ceramic ring is much popular as tower packing.
