Ceramic Saddle
12
Ceramic saddle is improved from the arc saddle, it changes the both arched surface to rectangular surface and makes the interior and exterior radius of curvature different, this construction overcomes the problem of nesting basically, it makes porosity distributed even and improves the distribution of the fluid , greater capacity and lower pressure drop than Raschig ring.

Ceramic Structured Packing
12
Ceramic structured packing is a kind of column shape and single layer corrugated packing,consisting of many moire pieces with the same geometric shape and parallel to each other. It is not only widely used in coal gas washing tower, fertilizer heat gas saturation tower, naphthalene washing tower, ammonia washing tower, but also as the support for heat exchange machine, catalyst, and suit for a big tower rebuilding/revamp.
