The outstanding structure feature is to change tooth type edge instead of Arc type edge. This change increases packings contacting gap and promotes air-liquid’s flow and dispersion. Owing to Ceramics have excellent acid and high temperature resistance characteristic, it is very suitable in High temperature and corrosive environment.Ceramic intalox saddles relate to irregular acid-resistant packing. The surface of the Intalox saddle is part of the torus. Compared to Raschig rings, Intalox saddles with the same size of packed bodies have a 25% larger specific surface area and a slightly larger free volume. Saddle-backed packing has less hydraulic resistance and greater efficiency, than the Raschig rings.Moreover,as ceramics are very brittle, it is very easy to broken in a long distance transportation. It is mainly used in petrochemical and RTO field, especially in the drying tower and absorption tower for sulfuric acid production.
